No DRS. No KERS. No rubbish. Just your head and raw unadulterated car aerodynamics.
Watch any racing below the top level and you'll see that. OK, you won't see
that sort of finish (you'll only get that on ovals or with bikes), but you'll get cars passing each other and dicing.
The fact is, the guys behind were
waiting for their pre-planned point on the last lap to make their moves (though Dempsey probably didn't quite plan it to fall into his lap that well - he only won as the others went side-by-side - he'd have stayed in fourth on most days). Is that racing? Good judgement? Strategy?
KERS is fine and here to stay (and probably in your average road car in 5 years). The aerodynamics will be more advanced than the likes of Ferrari would have had in the early-mid 2000s when they were dominating F1 and the racing was so poor, so I don't think that's the cause of the good racing. DRS I will agree with, especially with these tyres (without the degrading Pirellis the racing would be absolutely dire without DRS, but the combination of the two is too much).
Edit: Don't get me wrong, I love oval racing, but the standard in the Lights is just another feeder series, where you do see more action. F1, despite people arguing about pay-drivers, has a higher standard of driver, and as a result the difference between one driver and the driver in front of him is that much smaller, so it will be more difficult to have explosive finishes like that. While the cream rises to the top, it doesn't make for the most exciting racing, but we'd all be watching Formula Ford and F1, GP2, etc would have collapsed in on themselves if all we wanted was race after race of excitement.
The Ginetta Juniors is probably the most exciting racing on the BTCC package (well was when they had a decent entry list), but few turn up to watch it over the touring cars.
