I bought a Tesla in 2018 on my phone, only ever having seen one, and without ever having driven one. In a quiet/stalled moment while traveling.

But that says 1000% more about impulsivity coming to my rescue, with reckless disregard for the risk of regret at the first sign of boredom, than any trust in mobile interfaces.

I didn't (and would never) book the trip that cost a fraction of that on a phone or pad.
