I realise that some folk become very annoyed when tailgated, but I have to say I was more frightened than angry. After I'd safely reached home I was a bit trembly. I reckon it was the woman's expression and strange face-piercings. I've since wondered if she's one of those numpties who think the speed limit on a single carriageway is 70mph, whereas it most definitely is not, it's 60mph.
I've been looking up various motoring sites online, and most say not to do anything provocative, and not to touch the brakes etc. or slow down to annoying levels. They advise moving over to let the twit past, or turning off temporarily (a bit of a nuisance, but defensive driving is never easy!) My husband said he'd take the line of least resistance, with the aim of ending up with the stupid thing in front, not behind.
But fantasy is always amusing. I've imagined owning a Bond car and letting rip with rear-mounted guns, oil fountains and H2S gas. Then zoom off with a nasty satisfied smirk... Ha!
