Human: Is there a way to tell if my car is leaking gas? Assistant: 
There are several signs that your car may be leaking gas. If you notice an increase in the smell of gasoline, smoke coming from the engine, or a decrease in fuel efficiency, these could all indicate a problem with your car's gas tank. You should also check for any visible signs such as bubbling around the gas cap or rusting around the gas tank. If you suspect a leak, have a qualified mechanic inspect the vehicle and determine if it needs further repairs.
