I think a point could be made that larger cars are environmentally more damaging as well as more dangerous to pedestrians and other road users, in both cases due to there being a lot more weight of metal being moved around in larger cars (so, more fuel consumption - which in the case of electric cars is still indirectly causing some polution - and more momentum that needs to be removed to stop a collision or involved in the actual collision).
Not really the way the other poster was making his point but still provides a "Fuck cars" reason to complain about "government buys lots of large cars".
I've also made an argument elsewhere about how the higher values involved in corruption in the Procurement of Car Fleets compared to non-Car options might be incentivising state officials to go for cars and car-friendly policies, but that's not relevant for this specific thread.
There has always been lots of Corruption in the US (IMHO), but now there is also a feeling of impunity and no shame, so both more Corruption and it being done in more visible ways.
