For some reason, the bad ass image he has just makes me chuckle, took no shit from everyone, but damn right dangerous, you would only expect it from him, - yes, it's a bit silly to think like that, but I was a kid then, and I quite liked the daredevil - although Senna has done similar antics it's somehow different.
Seeing him countlessly take the fight to the silver bullet McLaren's in 1998 and 1999 sum it up for me. When he fought the faster Williams that was before my time. But in this day and age, I've not seen a driver make that much of a deficiet to faster cars.
The memory that sums up Schumacher to me, was that race in Hungary in 1998 against the two fast McLaren's, and doing a slower 3 stop strategy compared to the McLaren's 2, yet coming out in the lead.
That...and, how Murray Walker used to be in awe in him despite Schumacher being Damon Hill's nemesis.
