My parents taught be more about driving than our 'driver ed' teacher that was probably only teaching the class to get some overtime. The level of instruction is still stupidly low in this country, I doubt kids are even taught anything about driving a manual these days. I rev-match on virtually every shift, it's most definitely not something to 'worry about' if that's the way you've always done it. It's not some extra step, it's just the way it happens.
Yes, everyone bitches about the pedals in the ST but they're not that hard to heel-toe, and the harder you're braking the easier it gets. The position of the pedals isn't nearly as good as many 'drivers' cars but they work. I did install a spacer under the mount but it's almost too much. But it's not bad enough to worry about. Maybe if I did track days I'd figure something out but I don't so...I don't heel-toe much, normally I just slide off the brake pedal to blip the throttle for the shift then move back to braking.
Same thing w/ riding a moto unless it has a slipper, rev matching is done every shift.
