Hey! This could remove the issue ramp incline all together, actually.
I don't know. My ramp is slightly steeper in one section, and people can tell.LeChatNoir wrote: As in, how steep does a ramp become unrealistic to use for one in a wheelchair?

I think it's mostly up to the vehicle designers to make it possible to carry a chair or whatever.
I don't think it's a logistic necessity to have access lifts or ramps that can be operated solely by the person in the chair, because if there's a mutant vehicle there to be boarded, then there are going to be people there too.

My daughters little kid manual wheelchair is 25" wide. It can go over a one inch vertical lip without needing to pop a wheely, but even a short wedge shape is better than a straight vertical drop, especially when going down. Her chair can turn completely around in it's own length, which is 36". The wheels are closer together than that but her feet stick out in front beyond the wheels and there are handles behind the back wheels.
Someone with an adult manual or electric wheelchair should write, but I think the electric wheelchairs sometimes have quite small front wheels.
Since the ADA 1" in 12" incline is so gradual, there might not need to
much of a complicated 'make flat' system-- a 36" section of ramp has only 3" of incline on it. So, say, a 36" wide ramp could have an additional 12" on one side that has curved sections twist to gain 1.5" or lose 1.5", to make a series of flat shelves every 36". This twist is only in one plane and so the metal fabricator wouldn't have to do anything exotic to get the sheet metal to bend the right way.
Edit: Or, for vehicles that can't pull right up to the ramp, there could be gangways at some regular interval, say every 5', that have the right twist to them and could naturally fall up or down a little to hit the exact right height.

While you've got your thinking cap on we should probably ponder putting a gate in the perimeter of my art project. Hard to hop a 36 inch high fence with a wheelchair.
