I stallin hate this car. Beautiful chasis and dashboard but the handling is shit. Seems unfinished.
I don't know if you have seen the comments about pursuit mode at Zapper's KITT thread. It is pretty much impossible to enjoy the car without taking it into account. That being so, here goes a primer on it.
The KITT has two modes of operation. Below ~6400 RPM, it behaves like a normal slow car. Above that lies the pursuit mode: extreme, Niva-like torque without any extra grip. Driving the KITT is primarily a matter of keeping (and taming!) the car at high RPMs so that awesome straight line performance is always at reach. For instance, the proper way of doing asphalt large corners with the KITT is in second gear at 100+ mph. That would be run-of-the-mill weren't it for the fearsome traction, which means you need a light touch on both throttle and steering when exiting corners in order to avoid spinning. (There is always the option of shifting up one gear to delay the onset of pursuit mode and then shifting down to engage it when it becomes convenient to do so, though that is likely to cost a few tenths every time it is done.)
