@Cristian 1986 is a good example. i don’t mean beating with more points, i mean showing superiority dispite inferior equipment, which doesn’t always mean having more points. i would make a strong case that 86 piquet had a championship car and senna didn’t, but piquet still ended up behind senna in quite a few races and both were involved in the title race for quite a long time. comparable to, say, schumacher x patrese in 92, when schumi finished third but was clearly the better driver compared to the italian with the much better car.
and in 87, senna challenged piquet repeatidly, with an inferior car. even with nelson champion that year, most observers would agree that senna was, in fact, the better driver.
