I wouldn't try it while in motion. You will be in a ditch or hit a tree
before you know it. Contrary to what you may have heard WSJT really
requires a lot of work and patience to make a contact. You have to pay
attention to what the computer is doing and keep an eye on the screen. I
don't see how you can do that and drive safely. I have run WSJT on 6 at
W4NH during the contests and made a few contacts but that was all done
fixed, sitting in the comfort of a chair while having a drink. With your
setup you should be able to make some contacts. My first WSJT contact on 6
was with K5QE in Texas. I was here at home in Georgia running 50 Watts and
a 7 element beam. We made the contact in less than 5 minutes. Remember
that WSJT is a 100% duty cycle mode so you don't want to be transmitting
100% full power. When I run WSJT on 6 at W4NH I crank the power down from 1
kw+ to around 400 - 500 Watts. I could probably go a lot lower but when you
got the power might as well use it.

Subject: [VHFcontesting] WSJT for random contacts in contests?
Does anyone have experience using WSJT to make random contacts in VHF/UHF
contacts? That is, calling CQ on a specific frequency without skeds and
making contacts? Do you work enough additional contacts and grids to make it
worthwhile?
Can anyone relate their WSJT experiences while mobile? Is it possible to
make contacts while in motion? I rove in the contests and thought it might
be productive to try to make a few WSJT contacts while underway from one
grid to another. I can put out a reasonable amount of effective radiated
power on 6M, 2M and 1.35M, so I am not sure that is a problem. In the
September contest I ran a Moxon for 6M, a 6 element WA5VJB for 2M and a 6
element WA5VJB on 222 MHz. With 100 Watts to these antennas I think that
there is enough oomph to make some WSJT contacts, but does anyone have
experience actually doing this?
If there is no propagation, which there usually isn't in September or
January, the bands can get lonely out here. I am looking for a way to
increase my score. My experience is that with my setup, 3000 points is about
all I can do without some way to extend the range. - Duffey
