That's your opinion and I respect that. I will give you just one reason why I like them. Let's say some A-hole for some unknown reason merged into my lane and hits me but not hard enough to trigger an event. All I have to do is hit the blue button and I have proof he did it. Otherwise it's his word against mine. I won't get into a pissing contest with you over this. I will just say we are all entitled to our opinion. Can we just agree on that?
