PZEV legislative victory

[Nicholas Miller]

Tamper proof is sortaa relative.  Torx, tripple square, safety torx, etc...
there are varying degrees of fastner trickery to try and keep the average
joe out... but in the end there is always a special tool to get past it.
It just increases the cost of operating for small mechanics which really
sucks.

Tamper proof heads sound like a good way to have head bolts break, AND no
way to remove them to extract the broken one.  Genius.
