Some of the biggest abuses are still the "VIP" traffic more than anything else. Just look at the number of carts parked around the high $$$ chalets (like the HAI one) and you'll see where some of the unnecessary traffic comes from.
I'll have to admit to driving a golf cart during the airshow, but I tend to only be where people aren't allowed to stand.
