Some of the trams do have handicap access if in a wheelchair. Also can request a golf cart if necessary
There's handicapped parking and general parking. That's it. Unless you're a season ticket holder and purchased VIP parking. Or if you have media or race crew credentials then you would have special parking. But for your case, no, there would be regular parking. HOWEVER, they usually have trams pulled by tractors that can shuttle you from parking to the track. These are not wheelchair accessible BTW.
Yes
Yes they do.
They got parking if you're handicapped the other net you park wherever
