Not picking on you here bud, honest!
Is that not the same for every driver from every racing principle ever? You have to be a certain level to get a drive full stop, so obviously they're all going to be around the same level. He's a c*ck and I can't stand him, but Alonso last year in a poor Ferrari was outstanding to watch.
They're significantly different from everyday cars. It's like comparing a road going WRX to a Group N car, or a Fiesta 1.4D to an S2000 spec one. The only thing really carried over is a basic outline of the car, almost everything else is created from scratch.
Holy sh*t this. The best race for me every year is the LM24. There is nothing like it, four (well, three really) different classes all on the same track for an entire day. Being there is very special, but even just watching it on the TV is still a fantastic experience. It's all the best bits of proper racing (driving balls to the wall) combined with the tech and strategy of F1 (aero, fuel consumption, tyre wear) and the length of an F1 season wrapped into just one day. Utterly stupendous.
