Is there a standard solution for transporting bicycles inside vehicles?

There are too many variables to assemble a standard bicycle rack for the interior.

Some of the variable factors :
– Type of vehicle
– Available space in the vehicle
– Mounting possibilities in the vehicle
– Types of bicycles
– Types of bicycle forks
– Size of bicycles and width of handlebars
– Personal preferences

Nevertheless, there are already standard configurations (= only the base) for some types of cars.
For example:
VW Caddy, MB V-Class, Renault Kangoo, Citroen Berlingo, etc.
