    Okay, just back of the envelope math. Assuming the car is truly 550nm, so the blue car is 400nm, and the red car is 700nm… How fast is the car going?

    Napkin math says 0.27c.

    Δλ=λ(V/c)

    Now someone else can figure out the kinetic energy of the car and why the whole continent just exploded…

      It’s not on fire or melting the asphalt beneath it, so it must be really aerodynamic, and have really low rolling resistance tyres…

      Did you take into account that the car is not driving directly towards the viewer?
