I'm playing with keyboard as well and indeed at some tracks it's very tricky to find a good line into the pits as the steering help of the game always activates.
Regarding the Kyalami track, sorry, if I made the impression like I created the Kyalami track which I didn't
I'm no track creator, my only skill in this area updating existing tracks with new graphics like I did with some 1996 tracks years ago (Melbourne, Barcelona and Suzuka)
.
Funnily I also started to work on some 1992 too at this time (including Kyalami) but not had the time to bring them to release state, although, iirc in Estoril only two- three graphics were missing to complete.
