Tesla has enjoyed a head start in the industry's quest for the holy grail of hardware technology — the ability to upgrade and enhance features wirelessly through over-the-air software changes.
The electric vehicle maker has proved to its competitors that it can be done, and done relatively effortlessly.
As practiced by Tesla, over-the-air updates are done automatically, the same way upgrades arrive on cellphones. Using the technology, automakers can send vehicle owners improvements for their infotainment systems, safety features and even emissions systems.
But to get there, manufacturers must first create vehicles with electrical architectures that permit connectivity.
