Lift at red lights

* A SMART TWOFOR, driven solo, develops 150-pounds lift at rest.
* My 1st-gen Insight, solo, with tank on reserve, develops 204- pounds lift at rest.
* A Tesla Model X, driven solo, develops 1,050- pounds lift at rest.
* My Toyota T-100, solo, unladen, and with the fuel tank on reserve, at rest, generates 1,522-pounds lift.

If you're arguing what I think you are--that atmospheric pressure integrated over all surfaces, top and bottom, of a vehicle at rest produces a lift force--your conclusion is not correct. It doesn't matter the shape of the surfaces; at rest and with no wind ("in all conditions, by default"), the force resultant from pressure will be *zero*.

Stated perfectly by one, completely devoid of critical thinking, and ability of reading between lines for context, after given all information necessary for the understanding and premise of the thread.
You frighten me.
