More on autonomous cars

I
do not believe that level 5 autonomous cars i.e cars that can drive
anywhere and don't even have a steering wheel, will be possible if they
share the roads with human driven cars. They'll need their own roads,
or at least their own lanes. Even then they won't make an appearance
for many years yet.



Level 4 cars that are restricted to certain
areas and are not suitable for inclement weather conditions will be vastly easier to achieve. But, even here, sharing roads with human
drivers is perhaps an insurmountable challenge.
