The previous small BMW, 320d compact we had one in the family for a good number of years, fine cars.
Despite traction control its quite easy to promote a tail slide leaving a wet roundabout, the TC does usually cut power quickly when one wheel starts to spin, but as with LSD's when both rear wheels start to spin up even for a moment then the back can be starting its overtaking manoeuver before the system cuts in.
This showed itself quite plainly when the owner got her local chap to fit 2 new tyres on the back, yes Chinese ditchfinders which i soon got rid of when i tried it, not a car to fit rubbish rubber to.
Thing is when a FWD loses traction on or leaving a bend due to too much throttle or speed then invariably the car just starts to run wide (understeer), easily caught by just cutting the throttle or even if you don't TC cuts power and the car just slows down but usually stays in line.
When the same happens with a RWD then once slipping has started an oversteer can very quickly develop especially if under power, lifting off or TC taking action won't always stop the rear sliding out, the driver must be ready and know what to do to correct the slide...problem being so many younger drivers have never learned how to drive without traction aids now.
Nothing wrong with RWD at all in my humble, i prefer the driving experience (well full time 4WD is best of all) and i don't have the luxury of any TC or ASR on my old Benz, but its shod well and treated with respect, i too cut my teeth on old RWD cars.
I would advise any youngster to get some skid pan and professional training, in order to enjoy and respect their RWD cars not to be afraid of them.
