Unless they drive a Tesla...

a quick check shows that
at 2400lb and a cd of 0.34 (which is purely estimated)
you'll approximately make 60mph on a 10% incline and 90mph driving level with nominal motor specs.
Using motor peak specs you'll make 55mph on a 30% incline 75mph on a 10% incline and sadly no more top speed.

I could of course be completely wrong.
Motor specs are from Azure Dynamics pamphlet.
In my calculation I use the rolling friction (not the drag neither the weight) of a 4000lb car, so above values may be on the lower side.

Oh, and I hope I will not completely embarrass myself with my first posting here.

torque in Nm, speed in mph

What are the two blue lines one is dashed? Cool chart BTW

[Propellator]

The blue lines are the wheel torque available at a certain speed considering the gear ratio.
The dashed one for the peak and the continuous for the nominal motor specs.

The other lines show the wheel torque needed to negotiate the incline in percent over the speed achieveable.
