I've never learned to ride a motorbike (nor do I ever intend to, I want to live)
Same here. I got put off when I was still in primary school. A neighbour's daughter who was about 20 had a minor incident on a motorcycle and had one leg in plaster from hip to toe. That was over 50 years ago when traffic was not as manic. Made a strong impression, I'll tell you.
As for emergency vehicles and oblivious car drivers .....
It was only a couple of years ago when I was stopped at a set of traffic lights, second in line of the lane I was in when I heard the sound of a siren approaching. Knowing the intersection very well and the slowness in the change of the volume of the siren, I soon came to expect the arrival of a fire engine from the fire station up the road to my right. As it got closer, I noticed the light sequence and realised the fire engine should hit the intersection just as I would have the green light - and with the volume of the siren, everybody should just sit and wait as it made its way through the intersection. Sure enough, in the next few seconds it came to pass exactly as I had envisaged. All the traffic was stopped as happens during phase change, the fire engine came up on the wrong side of the road from the right and was visible - lights and siren and all. Perfect timing for a quick and uncontested passage through the intersection.
You would think.
Just at that moment, the lights changed to green for me and the person in front - even with the fire engine having made its unmistakable presence felt - started off. I could not believe it! The fire engine baulked and this character continued on, completely oblivious. I just sat there and let the fire engine through the intersection (as did everybody else) and turn in the direction I was going. It took off down the road, accelerating as best it could with the recalcitrant driver in front. I followed, but it pulled away from me and soon caught up with that vehicle. I then heard several blasts from the air horns which was very clearly aimed at that same vehicle - as it did not pull over straight away.
I rang the fire station later that day and offered to be a witness to this, but the fireman said that this sort of thing happens so often that they just shrug it off.
I do wish I'd had a dash cam.
