But 57mm will kill the bike in 1 hit when it hits because it has a 2x damage modifier. Jeep can escape because it is highely unlikely that 2 pak shots will hit it in a row, which will also only happen when jeepguy is retarded enough to stay in pak fire cone after first shot
Well considering that they are cloaked 90% of the time, it can be harder than you think >.<
And the pak shoots faster than 57 anyway
