Slow Pacing in Panzer Campaigns?

[76mm]

I try to stay away from snow and mud as they move at a snail's pace, as they should.

But I'm not even talking about mud--just "soft" conditions. Even in column on dirt roads with no mud, infantry can move at most 3 hexes per turn), equal to 1.5 kmph. Seems very, very, slow, and really slows games down to a snail's pace. Even mechanized units can generally move only two hexes in open ground under "soft" conditions....so 1 kmph for motorized units. albeit cross-country.
