Anytime Waze causes an accident, I'm going to start writing nasty comments.
What makes you think nasty comments would help if there's a Waze accident?
Because the morons that caused the accident deserve it.
That's a bit of an odd conclusion to come to. It's not like Waze caused the accidents or anything and using Waze is pretty common. There's nothing wrong with using it or any other navigation app while driving.
Nah, it's Waze's fault. I'm going to do it.
The person behind the wheel is the one that caused the accident. Waze just gives directions, and nasty comments won't change that. You can't blame a map app for not knowing where people or cars are in the road; that's the driver's responsibility.
