Stop car ramps from slipping

[the_weaver]

I once hammered four high quality hard masonary nails with almost no heads into my concrete parking space, behind the ramps, to hold them still. I worked on the car for a couple of days, removed the ramps and completely forgot about the masonary nails. A couple of days later I was sitting in the driving seat, just about to reverse out over the nails when for some reason I remembered they were there. That would have been four flat tyres for certain.
