Therein lies the problem with public transportation in the US. What do you do after you get to Tahoe, Santa Cruz, or wherever? Most of these places are devoid of functional public transportation, and rental car companies have long lines and routinely screw people over and overbook.
And will the FAA allow you with your tent stakes, hiking poles, bear spray, and camping stove with fuel on the Lilium Jet? (What else are you supposed to do in Tahoe?)
