It could be said that I am making an assumtion that is not supported by evidence, but I believe it is a reasonable assumption and I am too lazy to do the research to back it. However, it is easily disproved. Somebody just needs to show the vehicle code from one state that allows earphones in both ears. My argument is not necessarily that it is unsafe to do so, just that it is illegal to do so, and therefore it is not a strawman argument.
In any event, it most certainly IS illegal in California and I live in California so I will not do it. Of course, you can call my hypocritical too if you want, because I will admit that I do not stop at stop signs if I know there are no cars and I will sometimes roll through a light after stopping if is clear.
I got so confused while reading your arguments between uke and you that I forgot which laws you were fighting over

However I always find it easier to bias for the person who doesn't post massive pics with sayings on them.
