You are confusing the bill itself versus your argument against the bill. I am not sure I like either one.
I stand by two statements that speak to the weakness of your argument but DO NOT NECESSARILY support the bill itself either:
A: with the interstate highway system, bills involving autos are not necessarily “state” issues. Sorry, they just are not. I love 10th Amendment issues but not every issue is one of those. Just isn’t.
B: this is not “for the children” legislation. Not only “children” are at risk here. If anything, it may be to protect law abiding responsible adults from irresponsible children. The “for the children” legislation is always to protect the children FROM mainly conservative adults. Apples and oranges.
C for your info Interstate Highways belong to the states not the feds.
