Haven't written a review in years but your game made me annoyed enough to bother!
When using nitro it's almost impossible to even avoid the 2 cars blocking lanes, it's possible but you need insane reaction times.
BUT the 3 cars blocks CANNOT be avoided even when travelling at the slowest speed.
It just seems like a really dumb design decision...
If you're going to do that on purpose you really need to add in health pickups or something like that to give you a chance of mitigating that randomness.
At the moment even if you're good how long you last is entirely dependent on how many 3 car groups you get presented with. And even crashing into the has a random factor because the amount of damage you take can be small or huge depending on how you are bounced through the unavoidable collision.
I loved absolutely loved Driving Force 2 but this one is a big miss unless you fix this problem.
