When I'm cycling, I HATE red turn signals. It's so hard to tell at a glance - and sorry, that's all I've got time for as I also have to pay attention to the other moron behind me who might do a stupid right hook turn (it's dangerous, and it's illegal, at least in California, to turn right without merging into the bike lane - yet all the stupid drivers... sigh...)
Even worse, the U.S. has to have the stupidest turn signal regulations EVER, as they allow colocation of said inferior red turn signal with the brake lights. How stupid is that? Cadillac and Jeep designers seem to be the most fond of committing this atrocity.
Turn signals should be amber, and never in the same location as the brake lights. Period. The EU has this right.
(I would buy into a group mod for the Roadster).
