In my experience, chargers at rest areas are much more convenient than those that are near a motorway, but still need you to take an exit, even if they are close to the exit. In countries like France or Italy, for example, this always costs you additional time for having to pay the highway charge and take a new ticket when re-entering.

Especially on trips where your legs are not at maximum length, so you have some flexibility, it would be great to have an option to only use chargers that don't require you to exit the highway.
