pavement-u-coaster

Whilst walking around Tokyo at rush hour, I was struck by the thought of integrated pavement/road, so mixing car and pedestrians on the same part of land.

The pavement-u-coaster is a flattened D shaped tube, made with interlocking plates, that allow say a 5 degree angle difference between two plates.

For a card driver wishing to drive down the pavement (sidewalk if you're on that side of the Atlantic/other side of the Pacific from here) all they have to do it drive into into one end of the the tube.

The rollers running across the bonnet, and fitted on the roof-rack of the vehicle will raise the level of the pavement at a very gradual angle, giving a slight, but none the less pleasing, roller-coaster effect to the pedestrians currently walking on the pavement-u-coaster.

Now the city can do with fewer traffic lights, and pedestrian crossings, and more people getting...wherever it is they are going to....and good for very idle mexico wavers, as they can just sit down and hired vehicles will pass beneath them.
