My immediate alternative would be to drop a grape behind a tire.
Though the fact that it's edible is problematic. The rats (with and without wings) would enjoy my scheme.
Still, any cheap inedible alternative would work. As long as, when you squish it, it stays squished.
But that leads me to think: why not build it into the parking spaces? Glue something down that takes just over 2 hours to fully reinflate. Would need to be wide enough to ensure it gets run over. Probably want to be clever and make the reinflation not appear to be linear - once it gets to a certain point, it would stand itself up or something. Would be fun to design.
