Bouncy blackspots

Tyres are presumably recycled into those soft, bouncy bits of playground that prevent our children from being brought up by the school of hard knocks whence we adults benefitted. Also presumably, there are insufficient tyres to pave a country's highway system entirely in bounciness. However, there are also accident blackspots where people frequently emerge at speed and in an unplanned manner from vehicles and sustain undesirable body modifications incompatible with life or health (unless you're J G Ballard).

My proposal is to pave those small areas and the associated street furniture, such as litter bins, railings and bridge supports, with recycled tyres instead of tarmac, concrete and other unforgiving surfaces, thus reducing injury should accidents occur. The road surface would still have to be firm enough to support traffic, but even it could be made softer, and non-horizontal surfaces more so.

Then there are hovercraft of course.
