the Car helps the Driver by adding its Handling Bonus (at least in SR4A it did)
just as a Smartgun helps by adding its +2 Bonus
If You want a Teamworktest for the Car You should also make a Teamworktest for a Smartgun (or a Medkit, an Autolockpick,etc)
It just doesn't work this way
Not all vehicles have a handling bonus, though. Some have a penalty, many have neither. The Handling bonus is strictly the mechanical workings of the car - whether it's a fast, agile exotic or a big, lumbering behemoth that maneuvers like a drunken moose wearing clogs attempting to tap-dance its way through
Swan Lake with an orca strapped to its back.
That's not the same thing as the drone controller of the vehicle using its Pilot rating to assist the driver.
I would allow it, personally, assuming that what you're attempting to do is within the programming of the Pilot program in question. If it's an off-the-shelf commercial Pilot program, it's not going to want to cooperate if you want to, say, use the vehicle to run down a pedestrian, so turning it on will only hinder you and turn your check into an opposed roll. If it's a Pilot program that you've modified to be more amenable to breaking the law, then it can work.
And honestly, with failure at vehicular rolls tending to have dramatically disproportionate penalties, I don't mind some dice creep in that area. Just don't expect this to work if you jump in some jackass's random Ford Americar and 'jack it, Aiden Pearce style.
