IPhone app that uses camera to alert road changes or dangers?

My husband is a new CDL driver and during his training an instructor told him there was an app the used the camera on the phone to note speed limit changes, pedestrians, and risky car maneuvers.

Can't find it… Any ideas, apparently it's new.

Should I get the iPhone 8 or the 7?

I can either get the iPhone 8 or the 7, if I get the 7, I get more storage and the colour I want, but the iPhone 8 IS Really COOL! I dunno what to do, what should I do?

Gold or space grey for new iPhone?

Ok I've had the iPhone 6 since it came out now I'm planning on getting the iPhone xs max that's coming out but I can't pick a color between the 2 I'm not a huge fan of silver I already had gold on the iPhone 6 but I don't know if I want that color again or space grey.

Why do Canadians have computers and phones?

They obviously have no clue how to use them.

Please, never give a Canadian a laptop or access to any social media. They'll literally vomit all over the keyboards with their rants and poison. They need to keep their paws (guys) and claws/tentacles (girls) off the keyboard.

Yes, Canadians are keyboard warrior champions. Everybody knows that.

Sometimes I wonder how those retarded Canucks even manage to turn on a computer or iphone…
