You're not spending 30+ minutes charging on modern EV's (maybe some cheap crappy ones IDK)...I spent my summer holiday driving around Europe for 3 weeks, and charging stops were always <25min from leaving the highway to back on the highway. The actual charging time was often so short that we barely had time to get the kids to the bathroom and back before the car was ready to drive for another couple of hours. Having them at gas stations in Germany, where there's almost always a decent level of amenities (at least along the highway) is just fine and makes perfect sense.
