Yeah there's not a lot you can do about vehicles carelessly or deliberately overtaking from behind. I had a minivan do that to me last week (first time in over two years commuting) - it passed on the corner, hard on the gas, cutting close in just as we reached the apex of the left turn. Fortunately it's a rare occurance but you can see how it could very easily be fatal - it's a matter of inches.
