My wife has a big issue with our 70D : The tail lights are not on by default. Only front DRL. And it is not possible to save the setting with light always on in the driver profile. She is often driving late night/early morning and she sees A LOT of cars with tail lights off (cheap models without light sensors where the driver forgets to turn the light on). The light sensor in the model S is pretty good, and it seems that the light are automatic turn on the the wipers are activated. But still - when driving in the morning with fog she has seen several times where the tail lights are not turn on because there is enough light, but still the visibility can be 0meter due to fog. Why can't Tesla make it possible to save the light setting in the driver profil, or include the tail light in the DRL setting. I don't think that the tail lights consumes that much energy on a Tesla! PS I'm from EU. In Denmark from 1990 cars where required to drive with light turned on - including tail lights. In 2011 we adapted EU laws saying that only front DRL was reqired. EU soon found out that people forgot to turn on light in the dark, therefor from '16 all new cars must have a light censor. To me this was a BIG mistake not, at the same time, require tail light on all the time !
