3: The Flat Tire
If you have a car that has sat for years on end the tire can become damaged and unusable, sadly this person didn’t understand. “You need a new tire,” replied the mechanic. “No, it’s just the bottom that’s flat.” The customer pointed out that the rest of the tire looked fine. The mechanic had to give a brief physics lesson to help the customer understand that when the bottom of a tire is flat, the tire is flat.” – via Readers Digest.

The flat tire is an indication that the car sat for a very long time without having air. Or the tire was flat when the car was parked and the owner just decided against fixing it. Nevertheless, the flat fire is unusable and this happens quite often.
