I see that many drivers of big cars are unable to understand the subtle nuances of the OP and have assumed that she is referring to them even if they tow, rescue, breed legions of children etc etc
.
If I could afford it I might well buy a car that had specifications beyond my actual necessities - a camper van, a natty little sports number or something. 'unnecesary' doesn't have to be judgmental. But unfortunately massive cars in a very tight urban situations DO impact badly on other people, so an be inconsiderate.
Some other misunderstandings/ observations:
Valhalla - actually Insurance stats show that proportionately more drivers of 4x4s are found to be at fault in accidents than drivers of other cars.
4x4s may get less bogged down in snow, but are not better at getting up hills in snow. My Fiat Punto would get happily to the top while cars with big fat tyres skidded and floundered, and anything with RWD was in the ditch. 4x4s do not brake more reliably in snow than cars with small narrow tyres, either - just bigger and heavier as they slide towards thier target. There were loads of reports on MN in the big freeze about little cars making it to the top...
A Freelander is no bigger than an average car? I had to park in the Pay and display waitrose car park today as the free sainsbury's one was full, and I gazed at a Freelander and thought how enormous it was against the ordinary cars. Modest-ish next to the range rovers, X5s and XC90s, granted, but NO WAY the same as an average car!
Anyone who needs parking sensors to park a car, any car, shouldn't be driving it, imo.
You can get 3 car seats in the back of a Ford focus! And a wheelchair and a week's groceries in the back of a Punto, without the seats down!
If you drive these things for pleasure just say so - but please also be gracious and honest enough to understand that they do inconvenience other road users in places like central London.
