| Navigating in a car was a problem even when I started driving in the early 2000s, before GPS. - If you just had a map book you'd have to study it before a journey to get the likely placenames you'd see. This is surprisingly hard. - You'd probably forget to check one-way systems. - You could sort of guess where there'd be traffic, but for any major diversions you had to be very careful to follow the ad-hoc signs. Plus there's a high chance that you would decide you'd lost the way if the gap between signs was too long. - You really needed to know the major geographic placenames by heart. Even if you're not going to Manchester, you will need to know whether on your trip to Birmingham to follow the road to Manchester. Now picture driving in a foreign country. - Forget about estimating the time to get there. If it's a place you don't know your route will not be ideal. - Conveniences like the next petrol station off the road, forget it. |
I mention all this just because OP's article mentions the mid-80's Etak system [2] (Nolan Bushnell!) which I'd never heard about and had to look up... and it looked almost like having a Vectrex in your car that ran maps off a standard cassette tape. Pretty wild.
