In my opinion this is a realistic attempt at a rallying game.
The cars are meant to be difficult to master, and they are - well, at least to certain extent. Initially it is very frustrating as the car is almost never on the track, but once you have started to get a feel for the controls then things start to get better. As you also start to learn the tracks then things get better still as you work out how to get round the corners and obstacles quickly - dare I say it even at full throttle.
Watching your performances through the replay function will give you an insight into what you are doing wrong - and watching the computer controlled cars will give you an idea of what you need to do to go fast and stay in control e.g. you almost never have the wheel steady and straight for longer than a fraction of a second as you are always correcting for slides, bumps ...etc - watch those front wheels on the replay!
The only drawback with the controls is that you can't vary the amount of throttle, so its either pedal to the metal, or nothing. This makes the restart from the side of the road after a crash a little tricky at times - handfuls of opposite lock being the order of the day .... saying that, it does make doughnuts really easy to do!!
Learning the tracks is very important as the obvious shortest route is not necessarily the best - bumpy ground really comes into it here as the cars are in the air a lot of the time and, realistically, can't be steered while airborne. Hopefully I haven't put people off with making it sound too difficult - if it's any consolation my 7 year old son wipes the floor with me on this, although I'm better than him at Formula One 2009!!
If you want a challenging driving experience then this is likely to be for you - if however you want a simple kiddies racing game then you probably need to look elsewhere - Mario Karts maybe.
