Had my V1 for 2 days and it already paid for itself!!!
I was driving to work this morning doing 80 in a 55 and the Ka started to slowly increase as I was heading up a hill. As soon as I crested the hill there was a CHP on the right shoulder, engine running, ready to hand someone an unexpected bill. Even though there was a hill blocking my view the V1 still alerted me a full 1/4 mile ahead of time, otherwise I would not have had time to slow down. The traffic was moderate at the time and I may have been able to blend in regardless, but at 25mph over the limit I doubt that would have been the case. I've never had a moving violation before, but I'm assuming that a ticket like that would cover the $400 I just spent.
