[Terminator Salvation] Why did the motorcycles the Terminators rode have human usable controls?

Couldn't the Terminator directly interface with the motorcycle to control it, both being more efficient and preventing humans from using it? Also why did the motorcycle even need a driver instead of just putting an artificial intelligence in the motorcycle?

One thing to remember is Skynet, for all of its brilliance, isn't human.  Doesn't think like a human.  Doesn't behave like a human.

Seriously, Skynet set in infiltration robots with rubber skin and figured that would work because earlier infiltrators without human skin were total failures.  The rubber skinned ones were failures too, so then Skynet developed organic skin and even it wasn't perfect but at least was more successful.

That's kind of the way it operates.  Skynet will do the bare minimum that it thinks will work, and then when it fails Skynet figures out what it did wrong and then upgrades it.  

So to the motorcycle.  Skynet found a working Motorcycle and figured out how to apply an AI to it for scouting.  Some were lost, but overall the numbers were good so it keeps buidling more.  Eventually the humans figure out how to hack the devices, so they can ride them.  Skynet does a minimal redesign so that the manual controls, which were still there, are removed.  Problem is that it didn't change anything else, so if you can hack it a human can still just weld on controls.  If Skynet thinks this is still a problem, Skynet will evolve the machine so that you can't put on any human controls.

In short, Skynet is an evolutionary REACTIVE system.  Its programming will not allow it to make the quantitively leaps that humans do or even think that far ahead like that.  Meanwhile, it brilliantly predicted how human warfighting would progress and acted accordingly.
