Hi,
If I might add a couple of suggestions to the community patch, as well as the already suggested improved tail lights for civi cars, I would ask if you could please tone down the tinting of the windscreen and maybe add an adjustable seat?
The amount your avatar moves around when going over the bumps and jumps is annoying, it's quite hard to see through the roof! so if something could be done about this, that'd be great. (I understand these are rich idiots but not everyone rides with no seatbelt ;))
My final suggestion I'm guessing would require a shed load of time and testing to fix, but if all the road transition bugs could be fished out and squashed so you don't randomly dead stop/get spun out when cutting corners that be awesome.
Here's hoping they don't break too much more stuff with dlc2 for you to fix.
