Ah, cars. A highly controversial topic among the community it seems. I'm unsure where to even begin tackling that issue, but i'll start with player behaviour regarding cars.
I have been extensively researching this topic on the forums, as well as sorting through my own experiences in game with cars. There are more than a few suggestions, reports and topics regarding them, so i'll try and wrap a universal discussion about it in this topic, as it seems many if any of the issues regarding them have been resolved due to the fragmented nature of the reports.
But, on to behaviour. I'll recognize that there are some decent drivers of cars in game who want to respect the truckers that the game is based around, however the vast majority of players in cars are generally haphazard driving them, disrespectful, and ignorant towards other users of the road. They get impatient and act disrespectfully due to how slowly trucks accelerate and maneuver in comparison to themselves which creates a bad situation for everyone involved. They don't control their speed and crash into objects, other trucks and themselves. Players in the community have spoken out countless times about reckless behaviour.
While i appreciate the inherent use of cars in game (police, filler traffic to make the game feel more alive), I do not believe that cars as they are currently implemented in game are appropriate at this time. Some major decisions about accessibility, price (and speed!) are needed, as they are extremely detrimental to the experience of everyone else.
While staff cannot possibly be everywhere at once, there are still quite a few things that can be controlled about cars to make everyone's experience a better one.
