Putting aside launching, straight line speed, etc and the fact that some FWD hatches are allegedly quicker round corners, I know for a fact that I can get from Aberdeen to Ballater quicker than a Fiesta ST and most other cars for that matter, that's good enough for me. If you look at the complete picture not just track performance it's a very capable car.
I've had a similar experiences on the GSXR. On a ride to Tyndrum I couldn't shake a Subaru P1 on some twisties but over a 3 mile stint he was left well behind.
I agree it's not the car for everyone and I honestly don't care if others believe a Fiat 500 corners better as long as I get there 1st
