A couple of weeks ago, I had a slow leak in my tire. I know this because a little light on the dashboard came on alerting me to the problem. I’m no car expert, but I do know that tires are kind of important. So I immediately ran through some possible scenarios: a) panic and drive straight to the nearest garage, hoping they have someone on duty who can fix it; b) ignore the light and risk a blowout on the interstate; or c) make an appointment with my regular mechanic to get the problem checked out.
