[Star Wars] Why would the Trade Federation make vehicles that require droid pilots, rather than droid vehicles?

They have tanks and spaceships and the whole deal, but isn't requiring a spotter and driver (And presumably a gunner) a MASSIVE vulnerability that could easily be remedied by just giving heavy armor and ships the same AI as the droids? 

It just doesn't make sense to have robots and vehicles, when you can have robot vehicles.

It's likely the vehicles were designed with living crews in mind and the trade federation just added a little bit of software to make the droids competent (but only competent, anything more advanced becomes too expensive) pilots instead of hiring and training crews. Not only is it much cheaper, droids won't take a better contract with a rival group or drive their vehicles to the enemy with intention to defect. Company secrets are thus protected and a huge amount of money is saved not paying the soldiers.
