Walking on the water

Well it may only be a couple of inches deep but the fact the ice held my substantial weight was impressive. The dog and I had great fun cracking the ice and listening to the shock waves reverberate. 

On my way home the car told me my ABS and ESP were defective. Now I accept I don't have much of a six pack but how does the car know my psychic powers are rubbish?

(Turns out defective ESP makes the car virtually undrivable. I had fun getting home)
