I've been trying to pinpoint exactly why driving in Cyberpunk is a bit a pain in the arx compared with GTA 5 (it's closest competitor probably). So yesterday I booted up GTA5 and played it for a while (driving mostly). These were my (highly subjective, except for point 7) conclusions.
1 - Vehicle interiors in Cyberpunk are more polished and detailed than in GAT5. However, all the GTA5 vehicle interiors work flawlessly while some cars interiors in CP are broken (some have far too low viewpoints to the point you can't even see the road, others have so much brightness coming from the window you sometimes become temporarily blind).
2 - Vehicle sounds are far better in CP2077, but the volume is a bit too low on cars.
3 - Vehicles slide a lot more in CP2077. In GTA5 they're a lot more "glued" to the ground and require much more abuse to start sliding.
4 - Poland weather doesn't make it a very motorcycle friendly country, as clearly nobody at CDPR even rode a motorcycle. In CP2077, motorcycles handle exactly like cars, that's why they feel so weird. Motorcycles don't start sliding all over if you turn a bit too much LOL. They seem to have the exact same physics model they used for cars (ran out of time perhaps?). They're much better, in terms of handling, in GTA5. But they're much cooler in CP2077.
5 - The game world in GTA5 was clearly made with driving in mind. Roads are ultra-wide, turns are smoother and large. Neighborhoods look like a bunch of highways with buildings on either side. In CP2077, Night City looks a lot more like a proper urban setting, with tight turns, alleys, slums, a couple highways, etc. It's not made for high speed driving. But it's much more atmospheric, and even cruising at mid or low speed feels awesome.
6 - The sense of speed is a bit off in CP2077. Coming down the avenue at 182 miles per hour (300 km/h) didn't feel like I was going more than 100 (160 km/h).
7 - Controls are far, far twitchier in CP2077. This is the reason why driving in CP2007 is a bit of a pain. Even using a gamepad, a tiny bit of input translates into far too much turning. This is even more pronounced in motorcycles, where I can only use a couple milimeters movement before the bikes start sliding. Currently, tweaking sensitivity in settings does not affect driving. I set gamepad horizontal sensitivity to minimum, and while this affected the right thumbstick (turning my head view now takes forever), it didn't affect the left thumbstick (steering) at all. This is, IMO, the big issue. If this is fixed, most the other annoyances (other than the few broken interiors) will either disappear, or smooth out.
Conclusion: if they eventually fix the steering sensitivity issue, and fix the cars with broken interiors, cruising through Night City on a rainy night will be IMO the premium driving experience in any "non driving sim" game. Feel miles cooler and atmospheric than in GTA5. Even with the half- motorcycle physics model.
