I too am a CFR, and would love some kind of lights to get me through traffic. Frankly, I don't give a bugger what colour they are, provided that they let the person in front know that (a) I'm not a boy racer, but that I'd really like to do 40mph in a 40mph limit - and not the 28mph that they see as quite fast enough, and (b) I do have a real purpose in driving along this road. I reckon that lights would save me 30% or more of my response time on the average job - and that's without breaking any speed limit. (I'm not too keen on breaking speed limits as it would increase my insurance costs manifold - and the Trust wouldn't pick up the bill.) As far as drugs are concerned, I'd just like to be able to use such "exotics" as glucogel. If the essentially untrained bloke working next to a diabetic can give glucogel, then why can't I - given the correct training?
