Then argue for convenience/speed/fun as I write here[1], not in the conversation about fuel usage. Even your example, driving from Bucharest to Vatra Dornei, RO is 490 km (DN12; 1.41x) or 520 km (DN2; 1.5x) vs 347 km, hardly 2-3x the parent comment you're responding to, again keeping in mind that the airport won't be in the middle of the city. As for highway speeds, cars are calibrated to have the highest efficiency at highway speeds[2][3], so per distance, most cars will do best at reasonable highway speeds.
