By comparison, there have been a little over 45 road deaths on Grand Prix circuits since 1950, the last one in 2001. It's been 10 years since some has died on a formula 1 track, ...despite these cars being driven at 220 M/ph (or 350 K/ph).
To summarise, in the same eight year period between 1998 and 2006, 3,294 people died on Irish public roads with vehicles driving at speeds between 10 M/ph and 100 M/ph - 2 people died on Grand Prix private roads with vehicles driving at speeds between 100 M/ph and 220 M/ph (Paolo Ghislimbert in 2000 and Graham Beveridge 2001.)
The fundamental difference is that accidents which occur on privately run Grand Prix tracks directly impact both the profit and reputation of all individuals responsible for the service. This is not the case for Irish public roads, which the RSA (Road Safety Authority) controls - in fact the opposite is true.
If the RSA really wanted to do Ireland a favour and make the roads safe - they'll shut down and hand the roads over to the marketplace, where there are exacting and predictable consequences for the correct, and incorrect, management of services.
Imagine being able to say your country had 0 road fatalities in 10 years, like the Formula 1 representatives can.
