Yep, confirming this problem at my PS3 too! And low frame rate too, cars are overreacted with control.
Ensure your router or modem's firmware is up to date.
To do so, you'll likely be able to find help from your router manufacturer's website.
There are several solutions you can try in order to improve the connection on PS3.
Yea, I went through it again about a week ago. Tech support walked me through it when I first got the game. There are just invisible cars on the game. Cop and civillian. Just another glitch to deal with. Yes it can be frusterating, but honestly it has led me to witness some of the most incredible and funny crashes.
