Keeping things focused to technology, I suppose: Android Auto in my car. Two things that drove me nuts recently, all in a single 10-minute trip:

1. I pulled over and started typing an address. The car screen helpfully displayed a message - as it does every time - that I can use my phone's keyboard. This message completely blocked half of the on-screen keyboard, so I could not type out an address until it faded away.

2. I hit play on the music app, and my phone started playing the music out if its speakers.
