I've managed without them for years, and millions of people have managed without them for decades, they are just a novelty for the people who these days can't do anything unless someone spoon feeds them info.
What a ridiculous comment. Of course anyone (myself included) can manage without the tracking/apps. But they make things far easier, especially if there's a hold up on your route or less importantly if a enthusiast/spotter is trying to find a specific vehicle. Also i advise you check up on the meaning of novelty, surely in age where the industry is trying to get as many people to switch to buses as it can vehicle tracking and live bus times is one of the key first steps. I live on a route with a 20 minute frequency, i don't particularly want to wait 15+ minutes for a bus if i've just missed one. It's so useful being able to open my phone, go on to an app and then see how long the next bus is, that way i can leave my house just on time to get the bus rather than rushing out to find i've just missed one.
I'm not even going to comment on the "spoon feed" statement as once again it's ridiculous. However what i will say is that if anything is offered that can make a impossible/difficult task easier to do then of course i would take advantage of it without shame. The fact you pity people for doing is quite funny in all honesty. I don't suppose your car (if you drive) doesn't have a starter motor?
It's definitely handy to have one. Even though it's not always spot on I'd rather have a guide than have to guess especially as unreliability is fairly common with most of the services I use
The service i use although reliable has a inconsistent frequency up until around 11am, so it's near impossible to remember all the times as i said in my reply to Colin M it's useful being able to go on to my phone and see the times or if it's sooner how far away the bus is.
Although not really applicable in the "real world" the vehicle fleet number tracking is very useful as a enthusiast because if a certain bus appears that i need to photo i can find out where, what route and when it'll be somewhere within a few clicks. Where as before i would've had to go in to the city centre and wait for it or rely on other peoples sightings. Backwards people may call that lazy, i don't. It's useful and saves loads of time for doing other things.
