1. The radios on these cars go bad all the time - saw the number of backup buttons for when that happens?
2. KERS - you are limited to use it only for 6.6 seconds per lap - and, the driver gets to decide when to use it. Thus, it has to be a button.
3. PL: PL ensures that you don't go above or below the 75 KPH or whatever speed limit each track has. This zone is marked by a well defined line at the start and the end of the zone. I don't think that GPS is that accurate to turn this on/off automatically - especially considering the importance hundredths of seconds makes in this sport. Second, you don't want a car suddenly braking automatically or find the accelerator free automatically when the driver's not really prepared for the exact moment.
4. Oil: I believe this is in place for a 'what-if' scenario.
5. Tyre: Again, I am sure that this is in place because of the 'what-if-radio-does-not-work' scenario.
There isn't really any space to have levers anywhere else on the car like the hidden bonnet/boot switch and the backups also find their way to the steering wheel! ;-)
