mmmh the neighbour of the place I lived in last year wrestled his M5 for a good 20mins trying to get it out of the parking area after the big snows of last year. Me and and another dude offered to sit in his boot so that the rear axle would have some weight on. No weight on rear axle, no good grip in snow (or slippery wet roundabouts).
mmmh that's BMW sucker talk there
You can appreciate that RWD is good for tracks and racing, not for daily drive. I know one feels like a lil race driver with RWD, but if you drive and comply according to the current road regulations and speed limits it's not the best way of putting your HP on the road, if anything it can bite the inexperienced driver on his/her back. 4WD is still the best solution IMHO.
I have disagreed with pretty much everything else you have said so far, so it is no surprise that I disagree with these statements as well.
It is not sucker talk, it is an informed opinion and my comments are not based on studying a physics book and watching top gear, it is based on my experience of owning 6 RWD cars and 14 FWD cars. With the exception of the 1966 Triumph Herald 1250, the RWD cars were consistently more enjoyable to drive, below on or past the limit of 'current road regulations'.
As for your neighbours inability to deal with the snow, sounds like his problem and not RWD given I was able to carry on as normal in large snow falls in my E39.
As for biting an inexperienced drive in the backside, the only 2 times I have spun (unintentionally) were lift off over-steer incidents in FWD cars.
I may have been inexperienced at the time, but this notion that FWD is safer, better and/or good enough for daily driving is one side of an argument coin at best and ill informed twaddle at worst.
4wd may offer superior levels of grip and all the benefits that brings, but there are very few 4wd cars I would take over a well sorted rwd chassis for driving enjoyment.
All IMHO of course
But it is the one I have and see no reason to change.
