I don't believe it's necessarily the power the vehicle has, but as Seahawk pointed out with the Mustang GT analogy; certain cars CAN have too much power for their chassis' characteristics, and thus present a challenge to the less experienced or less talented drivers. Same may have been the case with the Hellcat that was balled up an hour after leaving the showroom. I don't know. I'm not sure if that Dodge has traction ctrl, or stability ctrl, etc... but those features go a LONG way towards making high HP become less of a liability to insurance companies, and the auto manufacturers

A modern Porsche can lay down 400hp, and make a make a pretty novice driver feel like a pro. Even though the weight distribution is decidedly right for snap oversteer, all of the driver aids, in some cases including AWD, make the car much easier to control. Alternately, +300hp from a 35 year old 930 could make Stig look like a rookie. Boost coming online at such high RPM, lotsa weight in back, etc...

I suppose that I think that there can be either too much horsepower, OR that there can be NOT ENOUGH car for the power on tap. Both could be said of the very same car though.

Also, a vehicle with lotsa power, a good chassis, and very advanced driver aids for controlling stability, traction, braking, etc... can still make a path thru the bushes in the hands of the wrong driver.
