I know a guy who has one. He has to continually blow in it for the vehicle to keep driving, apparently.
I kept hearing this weird sound on the phone one day while talking. I finally asked what that was.
He went with me to a Bible rally in one city. Had a spare ticket. While exploring the arena, we saw a bar. He wanted to go in. I convinced him that was not our objective for the trip.
That’s true. After so many minutes, you have to blow into it again.
One of my kids had this in their car and I tried blowing into it and couldn’t blow hard enough to where two more tries and it wouldn’t allow me to start the car! I wasn’t drinking, just wanted to see how to work the dang thing!
