Where I live, the highway speed limits are 65 and State patrol are always sitting near my house, often ticketing people for as little as 70. I set my cruise at 69. It's nice.

[–] [email protected] 10 points 6 days ago (1 children)

I mean there's no street legal car in the world that can go 420 so you'd probably just get that ticket thrown out. Still have to pay the court cost though which is bullshit.

[–] [email protected] 5 points 6 days ago (1 children)

People making those rocket-powered land-speed record breaking vehicles use this one weird trick to get out of speeding tickets.

[–] [email protected] 7 points 6 days ago

Another great tip is to drive at 54900 km/s so that all red lights are green lights from your perspective.

[–] [email protected] 82 points 1 week ago (4 children)

Lmao ain't no commercial car in existence that can go 420mph. Cop saved you a ticket if you're not an idiot about things.

[–] [email protected] 82 points 1 week ago (4 children)

I would expect that any commercial car can go 420mph if you drop it from high enough.

[–] [email protected] 5 points 6 days ago* (last edited 6 days ago) (3 children)

No, terminal velocity is somewhere around 110mph I think. Unless you're talking about sending it into space.

Edit: yes I have read more about this since making the comment. Big thanks to a mediocre education decades ago for what I thought I knew.

[–] [email protected] 2 points 6 days ago

Pretty sure that's terminal velocity of a falling human. It will likely be much higher for a car.

[–] [email protected] 2 points 6 days ago

Terminal velocity depends on the drag profile and weight of an object. So it actually depends what shape the vehicle is and it's mass.

[–] [email protected] 2 points 6 days ago (1 children)

To be fair, I did say “high enough.” Get it beyond the atmosphere and it’ll easily hit 420mph. Just know there won’t really be anything left for your insurance company to appraise.

[–] [email protected] 2 points 6 days ago (1 children)

I caught that and I tried to acknowledge it. But I think the implied part was that vehicles won't go that fast under their own power.

Sure, that’s why what I said was funny. 😉

Ok now I need to run a cfd sim to check the terminal velocity of a car...

[–] Corkyskog 6 points 1 week ago (1 children)
[–] [email protected] 5 points 1 week ago (2 children)

I unfortunately don't have a cfd program, nor the skills to use one yet. Should by next year, definitely looking forward to it.

[–] [email protected] 7 points 1 week ago

I need a 'remind me in a year' feature!

[–] [email protected] 2 points 1 week ago

Evil Kanieval the stuntman figured out the terminal velocity of a human to be around 80 mph or so I believe, i imagine a car would be same or less, although it would probably fall engine side first?

[–] sugar_in_your_tea 14 points 1 week ago (1 children)

If not, there's always trebuchets.

[–] [email protected] 10 points 1 week ago (1 children)

There are few discussions I have in my daily life that can't be made more entertaining by adding "If not, there's always trebuchets."

Thank you for enriching my future conversations!

[–] sugar_in_your_tea 5 points 1 week ago

If it doesn't work out, there's always trebuchets.

[–] [email protected] 11 points 1 week ago (4 children)

Terminal velocity is a thing that exists.

[–] [email protected] 3 points 6 days ago

if you drop it from high enough

Just go high enough that drag is negligible. :)

[–] [email protected] 9 points 1 week ago

Drop it from outside the atmosphere. It will hit 420mph probably

[–] [email protected] 9 points 1 week ago (5 children)

Well sure, that’s why I couched it with “I would expect.” My guess is that most cars, even the Peel P50, have enough mass to surface area ratio to reach 420mph. But I haven’t done the math.

[–] [email protected] 7 points 1 week ago (1 children)

Pretty sure I've never seen anyone else use the phrase "couched it" in this context. Well done.

[–] sugar_in_your_tea 1 points 1 week ago (1 children)

I mostly use it with couching lances in Mount and Blade.

[–] [email protected] 2 points 1 week ago

Also valid!

Looks like a human is somewhere in the range of 200-300mph, give or take a bit. A car is probably higher, but it really depends on orientation. I wouldn't be surprised if a car couldn't surpass 420mph.

[–] [email protected] 3 points 1 week ago* (last edited 1 week ago) (1 children)

Oh wow, you're right. I always thought terminal velocity for a human was 120 mph. That must have been something I read a very long time ago that just stuck with me. I checked just now and the site I found said that it's 89 mph spread eagle and 310 mph head down. I agree, that car is totally doing 420, dude!

Nope, still doesn't work. The fastest commercially available cars don't go much faster than 220mph, which is about 350kmh.

[–] [email protected] 6 points 1 week ago* (last edited 1 week ago) (2 children)

According to that list, the fastest is 295 mph ≈ 474 km/h

[–] sugar_in_your_tea 8 points 1 week ago* (last edited 1 week ago) (1 children)

If they were going that fast, they wouldn't be getting a simple citation that could be resolved in traffic court, that's straight to jail levels of recklessness...

[–] [email protected] 6 points 1 week ago (1 children)

that's faster than most helicopters, if they've got a long enough straight, they're getting away lol

[–] DannyBoy 3 points 6 days ago (1 children)

If they've got the gas for it.

A Bugatti Chiron can do 440km/h. If the 100 litre tank was filled at the beginning, then the car will travel for 9 minutes at top speed before running out of gas.

[–] [email protected] 2 points 6 days ago

good point

i guess if I've got Bugatti money I've probably got money for a helicopter of my own, why the hell am I going 440kph in traffic lmao

[–] [email protected] 4 points 1 week ago

Damn, there goes my pride in my reading comprehension skills. Still pretty dang close when all you have to do is change 'no commercially available car' to 'no reasonably available car'.

"I have proof my car can't go that fast"

Open and shut case.

[–] [email protected] 33 points 1 week ago (1 children)

You think. There was an infamous case in Hungary where someone was cited for allegedly going 260 kmh in downtown Budapest. In an old Ford Transit van. While reversing.

The police simply refused to entertain the idea that someone knocked the camera and it made a bad read.

They had to close off the street and demonstrate that the van couldn't get to 260 in reverse.

The most memorable thing of the whole case was the head of the police saying with a straight face "Hungarian traffic laws are not enforced according to the laws of physics", as part of the prosecution argument.

[–] [email protected] 3 points 6 days ago (1 children)

It sounds like they won the case, did they not?

[–] [email protected] 2 points 5 days ago

Only because the victim had a lawyer friend who worked pro bono, and it still took years.

[–] [email protected] 43 points 1 week ago

You in court: Because i was blazin bitches!!! .... (sticking tongue out, hands wide and making finger gestures)

Judge (looking at you weird): ..... five years no parol .... NEXT!

[–] [email protected] 21 points 1 week ago (1 children)

Cool cops put down 420. It isn't about speed, it is about weed.

(or did everyone already realize that?)

[–] sugar_in_your_tea 14 points 1 week ago

Yup.

And OP wanted 69 instead, the funny sex number, in case someone missed that too.

[–] [email protected] 5 points 1 week ago (1 children)

'68 is pretty cool though

All hail scogin

[–] [email protected] 2 points 1 week ago (1 children)

Damn, a wild the chariot fan

I had a bumper sticker on my old ranger that said
