I've done about 3k miles in my Z4, mostly longer drives around Wales. It's brilliant, I absolutely love it but I sometimes it terrifies me. It's my first sporty, rwd car and I don't know if I would be able to handle it if it got out of control. What's a good way to improve my driving skills? Can anybody recommend any driving schools, preferably on track, that teach handling a car like that? Or are there any videos on YT worth watching?
