Are Drivatars car specific?
No, you can train your Drivatar in a Ford Focus and it will be able to generalise your driving characteristics to a Porsche 911 GT3. Drivatars infer your ability relative to the capabilities of the specific car you trained in. That’s not to say it will not benefit from car-specific training every now and again – particularly if you are currently focussed on a specific car in your career at that time. And its also true that if you would expect to modify your line around corners to take account of significantly different power and/or braking characteristics of a new car, further training specific to that car would clearly be beneficial.
