People who nail the gas too much in the middle of a turn just don't know how to drive. Its not the car's fault. FWD is a nanny that keeps you from making that mistake.
First of all, most RWD cars have a much better weight distribution than FWD. This isn't a necessity of the design, but FWD cars are almost always very nose-heavy. Obviously, a car with all its weight up front isn't going to be able to turn very well.
Next, RWD allows a lot more control. Neglecting the throttle, any suspension can be set up to oversteer or understeer, but all production cars understeer a little for safety reasons. RWD effectively allows you to modify this behavior with the gas pedal. You can make precise steering corrections with your right foot. Of course you can overdo it and hit a tree
. FWD cars basically go from understeer to more understeer as you press the gas.
Now think of accelerating through a turn. This causes weight to transfer to the rear wheels. Your tires get more traction if there's more weight on them, so accelerating a RWD car increases the traction on the drive wheels (to a point), whereas the opposite effect occurs for FWD. This is important for cornering, but its also the reason that FWD cars are hopeless in drag racing.
Giving a RWD car a little gas in a turn actually anchors the car to road, giving a very confident feel. FWD cars usually feel terrible in comparison.
In terms of racing, RWD has a higher performance potential, but its also much more difficult to drive at the limit. You can mess up much more seriously.
