On dry roads, I agree but in less than perfect conditions, I'll take fwd anytime. About the only vehicles in mass production still using rwd are pickups. Every year I see a few wild tail out situations with them but I've yet to be hit. One woman I know keeps about 500 pounds of patio stones in the back to keep the tail down.
What mainstream vehicles now are rwd? I don't think too many. If I had it, I'd certainly get a limited slip dif to go with it - not a bad idea for fwd either.
The last rwd vehicle I had was an Alfa Berlina but it had nearly a 50/50 weight distribution. The bottom line is you have to have weight over the drive wheels. Technology can cover, mask and optimize but it can't make up for lightly loaded drive wheels.
Cheers,
