You know those spikes that are supposed to prevent you from going into the exit of parking lots? You can drive over this with your car without any problem as long as you go slowly. Your tires will climb on top of them like a curb and push them down. How do I know this? Rainy nights, no signs and two exits on one side of the parking structure one with the gate opened. Pretty much me not paying attention.
I’m not really advocating people go out and try this. The spikes are there for a reason. If you really want to get into a lot with spikes, take a piece of wooden board with you and get your friends to hold them down.
