Well this is what Brundle himself had to say when asked about his career:
I was always bemused as to why you never landed a really front-running car for the majority of your career, when your performances seemed to warrant one. If you were to have your career again, would you do anything differently?

Given that I matched the three great drivers of my generation – Senna, Schumacher and Mika Hakkinen – in the same cars on the same day, it is clear I underperformed my potential as an F1 driver.
There are a few reasons. Smashing my legs up in 1984 derailed my career progress, fundamentally compromised my fitness training programme and, most importantly, prevented me from left-foot braking when it was virtually essential in F1.
I am also guilty of not having had a 100% focus on F1 at all times and I should have engaged a more aggressive manager.
I have to balance that with my achievements with 10 podiums and clearly somebody felt I was worth employing and paying over a 12-year period. I was also lucky to survive three crashes where my chances were pretty slim. All in all I guess I wouldn’t change anything in that respect.
