Try understanding. The road was already designed to be safe at 80kph. They lower it down to 50kph because of folks such as the ones who brake at the green light because the count down timer for the walk signal hit zero. Or the ones who don't know where the fuck they are going, panick miss their turn and slam on the fucking brakes in the middle of a 3 lane road instead of pulling a u-turn 100m up the road. Then they try the bulshit of traffic calming shit by retiming the lights so every light in 10km stretch will be red when you get to it. Fucking phenomenal way to prevent irritation.
