Back when I rode, I made a little arrangement of LEDs around the speedometer in 3 concentric rings of ~32 lights. The blue LED closest to pointing North would light, the green LED would always point towards my home, and the red LED would point towards my destination (programmable before the trip). That's all I really needed. Basically a small version of a navigation arrow above video game characters. It meant that one glance at the speedometer gave me all critical information in one instant. The brain is really good at intuitively figuring out parallax, so if I was moving, two glances gave me a good idea of distance as well, though I experimented with lighting 1,3,5,7,9 LEDs as the destination got closer.

Sounds cool, even if somewhat likely to get you into a dead-end now and then.

Sounds like a business idea.

I thought it looked fun, but no way to justify the price.

£40? I guess if they get popular you will see the Chinese version at half that price, but it's hard to imagine a niche product at much cheaper.

The cheapest Garmin watch is about 4x the price.

Huh, last time I thought about it was the kickstarter in 2015,and I remember it being closer to £120.

£40 is very reasonable :D
