Honestly, the argument that “humans mess up too” is as non-sequitur as the usualy liberal argument:
“But, Americans kill American people too! If we get rid of the illegal aliens we’ll still have killers!” - ipso facto don’t bother deporting illegals.
Poor argument.
All cars are deadly, or have the potential to be deadly.
Objecting to them because they are deadly doesn't make any sense when they are just as deadly with a clueless human operator.
after all, it isn't like human drivers never not see someone.
There are plenty of reasons to oppose them, but one accident is not even the best one.
