I’ve never heard of this, but I’m sure there’s some jurisdiction that would probably limit you to only going to work or something if you have one

I’ve unfortunately had the pleasure of needing one of these interlock devices installed on my car back in 2010. It’s definitely been awhile but the device only limits where you could go if you had alcohol in your system, and that limit would be NOWHERE. If you were sober you just had to blow clean every 5-20 minutes and I could drive as much as I pleased. The option without the device was no driving except to and from work and maybe the grocery store 1-2 times a week.
