I drive mostly first person. I've used keyboard/mouse because my son pinched my controller and now I am using new controller I bought.
3rd person feels a little harder than it was but first person is pretty much the same. I like the new traffic system. It is much more immersive. The Ai is much better but it does still leave cars hanging sometimes. The scripting defo needs tightening up. Seeing a guy driving a fast sports car that is almost totally wrecked and on fire would have been great, if the driver had been a ragged robed skeleton laughing his head off but, just a guy in casuals sitting there like nothing was happening- not so great.
Drivers suddenly slamming on is best solved by not driving up peoples exhaust pipe. I did find it frustrating with the keyboard because acceleration is harder to control but, for the most part you know when they are going to slam on before they do and with a controller its pretty easy to avoid.
ie at lights, at the brow of a hill, at traffic, when you drive right up their chuffer etc
Frustrating sometimes? Yes but have you been driving round your local city lately?
I've had little problem with the police. None from driving incidents because I don't hit other cars very often but then I am playing a character who doesn't like to draw attention at work and also likes cybernetics to be a choice rather than a necessity. Getting away from the police, for me, has been quite easy although I did once have to incapacitate an officer. I haven't been past 3 stars so I cant speak to what happens then.
I've not done any real car combat yet other than a very satisfying drive by shooting/hack of a small Maelstrom group, but I imagine I will revert to keyboard for that and one thing I would like to see is some way to have a cruise speed. It could be as simple as acceleration stopping once you hit say 40 and only continuing if you quickly release and press the forward key. Driving with keys involves enough tap dancing as it is. Not having to tap out the acceleration would help a lot.
The sounds I did not like at first but they have grown on me apart from the new preorder car which does sound good but always gives me the feeling I am being attacked when it reaches a certain rev count. Maybe just tone them down a bit.
