Wouldnt work, would just lead to car park rage.

Images of people speeding around to get to a space only to find someone else had got there first then booting it to get to the next one.

That's an oddly novel and surprisingly simple way to help with parking, although it does have it's downside, world helium stocks (as in, in a ready to use state) are dropping* so whilst the balloons are helping oil stocks, they're not helping helium ones



*IIRC the US government used to have a huge store of it (I think it was a by-product of a military manufacturing process or something), but the US congress decided to run the stocks down, so the price dropped and people stopped collecting it as much when it was a by product of other processes (things like oil drilling).
