Thats a fair point but trucks are generaly a soft target. Front shot damage is likely to engine or driver side shot need to hit something solid like the chasis or sails straight through with minimal damage. Might hit a few passengers but trucks pretty intact.

Ages back saw a program dispeling Hollywood myths in which they fired light arms at close range at an modern civilian SUV, pistols SMG at under 500m. The idea was to dispel the myth of exploding vehicles.
They were surprised as shots were mainly aimed below the glass line as it drove past so repeated the test with semi auto rifles.
In both cases the vehicle was still driveable though the radiator was gone so not for long so concluded to stop it you would need a lucky hit on engine management box or some such.
They also found modern vehicles with all safety gear like airbags steel crash bars etc designed to soak up energy did just that.
The first test the crash dummy was hit once but the impact was so slow it was a very minor wound, fired 500 rounds if I remember.
2nd test it was hit 3 times but only 1 bullet had enough energy to cause a serious wound & it was not life threatening, the adreneline rush of the moment would have left the driver capable to continue.
Conclusion if its close get the shotgun out of the squad car & shoot for the glass.
Also said in an older vehicle the occupants would probably have suffered worse due to less junk on the vehicle, safety gear wire looms etc but the vehicle its self would probably have survived even better wth a proper chasis & simpler mechanics.

Was a TV program though & firers were local SWAT team so probably some ex military
