there are already electric super sport cars
that drive at 400 km/h
and it's just a question of time
before highly aerodynamic electric fully autonomous family cars
with batteries and engines in front of and back of car instead of under car
to keep the passengers lower and closer to the road
in order to decrease air resistance
will drive at 400 km /h
and people will want to travel quickly
between work, school, supermarket and home
so that market demand will change how motorways are organized
the two inner lanes in each direction
are without speed limits for fully autonomous vehicles
while the two outer lanes in each direction
are for human driven vehicles
sleek fully autonomous electric vehicles
travel at 400 km/h in the two inner lanes in each direction
while fully autonomous electric semi trucks
human driven regular semi trucks
and human driven gasoline cars
travel at 110 km/h in the two outer lanes in each direction
the slow cars in the outer lanes will be geofenced by electronics in the cars
so that they are unable to drive in the fast inner lanes
and thereby slow traffic
the high speed inner lanes would be accident free
because only fully autonomous vehicles would drive there
and the slow outer lanes would be prone to accodents because of human drivers
but the entire motorway would be monitored by ai
that warns both fully autonomous vehicles and human driven vehicles
about road dangers such as human accidents
