I took some vehicles for driving. Ok, no problem with the very high speed, i even liked it. But HOW THE HELL can they be steered? I cannot seem to be able to drive them normally, without bumping on something ALL THE TIME! Don't get me wrong, i like wrecking both the car and other things around me, but i really need to drive straight, when i want to drive straight! So, may i ask, is it even possible in the first place, to steer the car with mouse and keyboard adequately enough, so as to drive it like a normal car, if/when you want to do just that?

Also, does (car) steering and movement bear any resemblance, of 2, to that of 3, or there it is different?

SR2 steering on PC is notorious for being like that for many people. I don't have much of an issue with it myself, but it's something I've heard from others.

The vehicle controls in SR3 (and beyond) were changed and I haven't heard of any real issues with that.

I just started playing SR2 for the first time a couple days ago, and I have to say the car steering is pretty bad, at least with keyboard and mouse. The problem seems to be that a single tap of the key changes your direction of travel by roughly 5 degrees, which is way too coarse. It makes fine adjustments impossible, which is why it's a huge challenge just to drive straight, even on a straight, flat street. Other than that, it works okay. I don't have much trouble getting along once the action starts, since braking, accelerating, and big turns aren't too hard.

Some vehicles are a lot harder than others, though. The Magma is almost impossible to control because it's so twitchy.

If the driving in SR2 had succeeded in being a little more like Carmageddon it would be one of the most fun games I've ever played. It's still a lot of fun.
