The driving in Transformers is flat-out terrible. You'll careen out of control into buildings, skid through turns ungracefully and generally feel like an ass. You can't even reverse in vehicle form, which makes the dodginess of the driving engine even more frustrating. While it's slower plodding your way on foot, getting around on wheels takes you out of the game. That's a damn shame, considering you're always being timed and that many of the game's characters are cars or trucks of one sort or another.
