Hi, I think it would be nice if ramps would be spawned in the same angle as your car is in. This would open up a lot of "[DM]-like" possibilities using only the default SA map. It's pretty boring the way it is right now, there is no variety in ramp races because it only makes sense to spawn them on a flat road with the way they currently work. This could be a seperate mode, Ramps2 or Newramps, to not mess with existing races.
Here are a few examples of what I mean:

An additional improvement would be to give players the ability to select the kind of ramp they want to use in buildmode.
