That defeats the purpose of on-demand autonomous if it needs visual markings at every point in the city.

There is a good reason why aircraft has not placed engines on the wing tips. Why is electric motors any different?
Landing a VTOL aircraft at random places in a city is a delusion. Anything heavy enough to carry people will create more noise and wind than bystanders will tolerate. The laws of physics do not yield to wishful thinking. Urban VTOL service will operate from (mostly) rooftop helipads - look at it as cost-reduced helicopter service.
