Talladega Nascar

[Fraser]

I watched Talladega this morning. Can't say that I've watched much Nascar (only on pay TV before) but now it's available on free-to-air TV here in Australia. What's with the bump-drafting thing? Surely an accident waiting to happen, as it turned out. Is this a regular thing? I understand normal drafting but to jam the nose of your race car up the rear of the guy in front and unsettle his car? Surely it should be a penalised ... a drive-thru penalty or perhaps a black flag for repeat infrigements ... on safety reasons. Or do the spectators only come there for the crashes, and the cars are that safe that drivers don't get hurt?
