Given all car makers are investing in driverless cars- why don't they install sensors or guide-wires into roads to mark lanes, etc. the next time they are repaving/repairing roads? won't that be much safer than having to rely on cameras/radars .
Roads are typically resurfaced only once every 15-25 years, and in many municipalities, shrinking budgets mean that some roads are just outright being closed rather than being maintained.
