Out of curiosity, how did the tech deal with things like frontage roads that have much lower speed limits than the highway right next to them.

- adhesive_wombat 4y agoBasically, they haven't, or at least they hadn't 4 years ago when the car I have with it was made. Diving along a free flowing 50 and having it decide it's now a 30 because it saw a sideroad and drop a gear is semi-regular. The second most dangerous thing it does after having a touchscreen. It also manages to read 45 sometimes but I have literally never seen a 45 sign.

- bearmode 4y agoIf embedded in the sign, what if the sign itself is rotated or damaged in some way?
- withinboredom 4y agoOur prototype just screwed onto the sign post and could be aimed that way. We never added it to the prototype, but having an accelerometer added to detect movement and shutting down/calling home would help with damage or vandalism.
