I hate yellow cars, and it seems I am not alone !.
Initially, I had no colour preference for a car. I was 16. I just wanted one that moved. My Toyota Corolla was sunshine yellow. Bright, bilious, happy, sick-making yellow. I loved it. For three days. Then a drunk guy smashed into it. It got repaired, but it happened again.
The thing was like a magnet. It was the most obviously bright object in any given setting. I think it made angry people even angrier. It was like driving a moving target. The sunshine and cheerfulness of the neon yellow had a far less than calming effect on the (then emerging) phenomenon of road-rage.
(Actually, I fear perhaps it may have contributed to the problem. Caused it, even. The last thing anybody likes is being faced with some dozy bollocks who insists on being stupidly happy when their own world is going to hell, and I think my car was the vehicular equivalent of the cheery idealistic idiot).
I sold it soon after to a friend who knew it's history and thought I was just being paranoid. It met its' untimate end via a ramming from a little man with a big car and an even bigger problem with the world (which he had attempted to drown via a liquid lunch before weaving unsteadily all over the road for a few miles, then gave into and targeted 'the driving banana').
Luckily, the new owner was unhurt, but I can't say the same for the car. When she phoned to give me the news that the smiley-on-wheels had breathed its' last, I admit that, despite its' good intentions, I was rather glad to know it was out of circulation. I mean, imagine if I was still driving it now ?.
