(Loyal Readers may recognize these cities as the homes of Register.com and Google.com, not a surprising coincidence given the Space Alien's long interest in modern technology.)
The Space Alien normally travels at tachyonic velocities exceeding the speed of light, but there was concern that bringing needed information from Florida to California in this manner could totally vaporize these valuable files!
Commercial airline travel was not practical because many commercial airlines had cut back on flights due to COVID-19, and also because the Space Alien has encountered difficulties with commercial airlines (mainly involving disputes over bags of peanuts).
So the Space Alien decided to take a leisurely drive to the new internet headquarters with the valuable files safely packed in the trunk!
