Yep. Nissan and the BMW z4 are kinda the easiest on my head too!What car are you using Des? I'm pretty much in the same boat and have trouble concentrating for 60 mins without making a mess at some point, but I find something like the Nissan is a lot more forgiving as it tends to be a bit more understeer'y than some of the others, so rather than a complete wipeout I end up just doing a little off-roading
If I get my rig wired up today I'll probably ask to join in that car if there is still room
I like the z4 even more due to the nice overview from the cockpit and it's not as heavy afaik so a missed braking point will only cost time but you'll stay in control.
Worst for this are probably the McLaren, lambo, Audi.
McLaren is a bit beasty overall with the rear and you need to push to keep up the pace due to lack of top speed, lambo and Audi like to push wide after missed braking points so you wash out, go wide, overrotate and slide into the next barrier...
