I think it's nearly trivial to have a system with much higher (2x? 3x?) traveling speeds: Rent a private jet. Doing this in a climate-friendly manner is merely (;)) an engineering challenge, cue synfuel. The real challenge is in scaling this up to the masses in a economical way. The frustrating part is that air travel is obviously the best way to get people quickly from A to B. Humans have just the right size and weight. There's so much space available in the skies that congestion only is a problem at the nodes. Safety is great because everyone intuitively understands the risk. Speed is maximal and, most importantly, the amount of required infrastructure doesnt scale linearly with the number of connections. Yet, air travel is seen as obscene in modern society because it currently relies on fossile fuels. I fear it will never lose this stain. What we're currently lacking is a strong movement to CO2 neutral, large airplanes. I believe if we'd focus on air travel the resulting solutions would be tremendously helpful to free other sectors from carbon emissions.
