increase the magnetic field strength or increase the shaping movement ... yes
what sort of vehicle ?
I suspect you will find that extremely difficult as a person cannot sustain the input power requirements for very long
I have seen threads on this before and the amount of power/energy an avg person can generate through arm/leg movement
before tiring .... it isn't a lot
Others may remember said threads or other related info

... why am I thinking this thread is eventually going to wind-up in our new 'twilight zone'?
I also have seen articles and references considering this. I think it's a part of the human condition, you
should know however, that you're not the first to imagine what you want to do.
The interesting thing I have noticed though, is that over the years mechanics and electronics has advanced so
much, that many things originally considered impossible, are now found to be potentially attainable.
Who knows, maybe we'll be seeing an answer for you here in a few years.

To illustrate @BobK 's point:
A 12V dynamo is connected to a DPDT relay, which feeds a heavy load (bank of lamps).
Dynamo is operated via pulley/belts by turning a crank.
No load - smooth sailing, easy to crank.
Energise relay (load connects) - suddenly you're "straining" against the dynamo & work-load.
(This was one of our school/science projects).
The E** series of electric locomotives use this feature for electrical braking,
forgot now what it was called (c. 1980's).
