I agree with the sentiment of this post, but to be fair, you can also carry 3 or 4 passengers in the left vehicle, as opposed to only one in the right.
The main problem is the US fuel economy regulations actually encourage manufacturers to build bigger trucks and SUVs so they get classified into a category that has looser fuel economy requirements.
A few months ago, I would have agreed with you. I own 3 hifiberry products and they are indeed awesome. Their own OS is great and they also worked very well with other software. But then I bought a couple WiiM minis. While it's fun to hack around with the pi, the WiiM just works and it does a couple things I could never get the pi to do. In particular, Qobuz streaming in high def and synchronized multi-room streaming.
