Just plain daft behaviour. Could understand if the car cut into the cycle lane without due care but that doesn't appear to be case in this instance. I have actually been close passed by an ambulance a few times, ironic to say the least. One thing I have noticed is that good ambulance drivers don't use the siren when overtaking cyclists (usually) when on a call; this is really good practice & I always give them a wave.I know it's bad form to quote yourself, but I experienced a prime example of that being discussed in the above quote this morning whilst driving out of London. I was on a road where the left most portion of the road is painted up as a cycle lane (piss poor idea IMO, but there you go). An ambulance with sirens and lights was needing to get down the road in the opposite direction to which I was travelling so both lanes of slow moving traffic moved to their left and into the cycle lane so as to let the ambulance use the middle of the road to get through. We were all stationary for about 30 seconds except for the cyclist in front of me who was trying to squeeze past the car in front but was unable to do so as the car had pulled left for said ambulance. He then started bashing the roof of the car and yelling that none of us should be in the cycle lane. The driver got out and explained about the ambulance to which the cyclist said he didn't give a shit about... cars aren't allowed in the cycle lane. The driver then lost it and shoved him off his bike. Fortunately things then calmed down, but... well this is what happens when two idiots meet! Neither helped the situation and it just makes me exasperated to be honest. Later on the M11 I watched as a van tried to stop a car joining from a slip road as he might have had to slow down by 5mph (it was busy) and then they spent half a mile beeping their horns and gesticulating at each other.... again two idiots... Sigh! Life is just too short for this sort of crap!
It's amazing how frightening it is when you get beeped from behind when cycling, it always causes an involuntary flinch from me.
