Dashcams.
Ive got a couple in my cars, bought and installed as a result of a monumentally idiotic Bulgarian truck driver side swiping me and pinning me to the front of his truck at 50+mph. The result was a contested claim and my not getting my excess and NCD back for 2.5 years.
However, I've got to say that I'm not "that" comfortable with having big brother in my car. My righteous indignation at other road users being inconsiderate, self important, dangerous and breathtakingly stupid is without equal, so the ability to "catch" other people in the act of doing some of these things is very compelling and is I suspect a principle motivator for people buying these things.
But, I'm not naive enough to believe for even one minute that I'm a perfect example of law abiding motorist myself. I speed on occasion, I even succumb to the temptation of overtaking the dim witted and ignorant using the inside lanes every now and then and if you catch me on a bad day I'm not averse to rigorously defending my own roadspace when other people can't or won't decide what lane to be in.
Don't get me wrong, I'm not a habitual and regular law breaker, but let's face it, when some mouth breather brings the traffic flow to a crawl because they're sticking like a limpet to the offside lane, It's often easier to simply check your mirrors and go round them. Problem is, it's illegal, and my dashcam (Sword of righteous revenge over the dumb, retarded, dangerous, and people I really don't like model number #1) is recording the event in HD technicolor for posterity. I'm not sure I like that idea, but I can be pretty sure the police road traffic units are loving the fact that a growing number of RTC's they attend have a non encrypted cache of HD footage of the event just ripe for showing the jury.
Am I just being unreasonably paranoid?
