Hybrids do make use of the battery and motor during highway use. When going downhill the engine will shut down and the battery will charge. This charge will be used by the motor on the next uphill to reduce engine use.

For plug-in hybrids with their large batteries several miles of all electric range can be generated on a long downhill.

Ford did an update to the MyFord Touch infotainment system last year this way. Downloaded a bunch of files onto a USB drive, plug into car, wait 20 minutes. Since it uses an automotive version of Windows CE of course it needed to reboot a half a dozen times during the update. But for power-train related updates you have to take it into the dealer.

We use USB flash drives for a data logger. Most of the time the data is being buffered in the ARM based Linux board's RAM to save power. Once we get a complete file's worth (4MB at the present) we power up, validate, write the file, and power down. Supercaps have been a lifesaver. There's even enough capacity to do the write cycle if the flash was powered down when a power fail is detected. That allows to not lose whatever what was already in the RAM buffer.

When you don't know what you are doing, do it neatly.
