That's about as much as I want to drive in the space of a single day. Conceivably however, automated driving could mean doing longer distances. And at a cost much less than an airfare - just a lot more in time.
NEDC (too optimistic): https://en.wikipedia.org/wiki/New_European_Driving_Cycle
WLTP (better than NEDC, still a little optimistic): https://en.wikipedia.org/wiki/Worldwide_harmonized_light_veh...
EPA (the most conservative): https://en.wikipedia.org/wiki/FTP-75
The WLTP figures are okay, but I think EPA test cycle is the most useful because it's the most consecutive and most representative of real world driving.
Route planners (ABRP, previously Tesla) will not let you drive 300km without charging, because you would arrive with less than 10 % SoC.
- You don't need to rent a car on the other end.
- You can take all the luggage that fits into the car. (even if there's a bottle of water in your luggage!)
- You can stop along the way for some decent food and a good leg stretch.
- You can listen to the radio without headphones and roll down the windows for some air that won't dry your skin out.
- No fixed schedule or chance of missing the trip if running late.
I don't think people fully appreciate yet how amazing full, unsupervised electric vehicle autonomy might be.
