To do what he did after suffering a life changing accident which rendered him tetraplegic at the age of 44 is truly amazing. I particularly like this fact (courtesy Wikipedia):
“In May 1994, following the death of Ayrton Senna in the Williams FW16 at Imola, Williams was charged with manslaughter in Italy, but was acquitted after several years. Since Senna's death, every chassis since the Williams FW17 has carried a tribute in the form of a small Senna logo on its front wing supports, or nearby.”
Respect. RIP.
