It realy depends, its the barstow and the moonhawk in very powerful configs, in "normal" power configs its ok to drive. (i dont have steering wheel, i use a ps4 controller, so its harder to control throttle feeding)
Interestingly enough, I find the Bolide much easier to drive compared to any turbocharged 200BX. But I am also not at all good at drifting vehicles.
Gotta be the Bollide and Barstow, they both spin out terribly. For unstableness definitely the Roamer, the centre of gravity on that seems terribly high.
If were talking about every vehicle and versions of said vehicles it would be between the Barstow kingsnake, Bolide 390 GTR, Pigeon 600, 200bx demon and ibusiu covet skid plate.
Just a example. All the other vehicles can do that except the pigeon. Also keyboard makes it super hard to drive straight.
For me, probably a big turbo version of the 200bx, because of it's unpredictable turbo lag, and is near impossible with a keyboard. Like, if you tap the throttle you could be fine, but the moment you try to go around a corner (like a wide corner) you run the risk of the turbo giving boost in one big blob mid corner and could cause snap oversteer. Even with a gamepad, if you don't know proper throttle control you won't have a good time. For example, if you have a demon running 48 psi max, even with oversized slicks if you drop the clutch you can easily do a standstill burnout. Although with some decent downforce (like the latest update added a wing) it can be manageable. For the Barstow, it's difficult for a lot because of it's simple rear axle (well one of the reasons) and this is also the case with the mustang. When coupled with big power (supercharged 423 ci big block), and instant power as well (because it doesn't have turbo lag) It can become a widowmaker for sure. Oh, and it being a typical muscle car with a front engine RWD layout can also make things worse. Oh, and no ESC, no ABS and normal road tires won't help for both cars. Pretty much the same case for the Moonhawk as well.
At first I thought the Civetta Bolide was the hardest. However, with AWD . . . . . . It becomes super predictable and easy to control.
I don't know how you guys are forgetting about the traffic barrel. When I throw it into a corner, it feels like it has no brakes.
Its actually this thing: Its soooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo slow, thats why its the hardest to drive because will take a year to ge to your destination, and it tips over when you turn it with some speed. But its the hardest because its slow,your patience is thrown by the window and then you crash it, thas why its the hardest. --- Post updated --- Update: But its a great mod and its good for dealing with used car dealers that fool the costumers
