"Giant" and "Steamroller" might sound redundant, but both are needed for this idea. Using fabric similar to that of inflatable "bouncy" houses that kids play in, sew an extra large steamroller. Fill it with air. It will have to be big enough to support your weight as you drive it, and a simple motor to make the rear wheel roll and provide movement.(I guess it may also require a fan that continually runs to keep it inflated.) Then go to a beach or a rock concert and run things over for fun. People will flee in mock terror as you then gently roll over them at 3kph. With the correct material, it could be filled with helium to support your weight more easily.

It would be soft enough to push up when the large front "Wheel" or barrel rolls over you. The only danger would be if the vehical would stop on top of someone and they don't wiggle out. Just put a warning sticker on it somewhere I guess.

Crazy! I love it! If it was full of Helium to be almost neutrally buoyant, you could do massive bounce/jumps à la monster trucks, except on/over people, trees, small buildings, etc.

This always gets a minus from me.

It would need to have a volume of at least 100m³ for this to work (~4.6m x 4.6m x 4.6m).
