I don't know what the statistics are in the west but I have followed the Lynx lawsuits in Maine and there were more Lynx killed by cars then were trapped. I believe their incidental take permit was 5 over 5 years. It would follow that cars could be banned in the lynx recovery areas. The DMV has no incidental take permit.
Of course we know that will never happen but it makes one wonder why trappers are held to a higher standard.
Incidentally a lynx was killed in WA last year by a night hunter. That is why this year there is no night hunting for cats allowed in the lynx recovery area.
