Here are my 0.02 pennies on why this won't work.

Most modern cities and towns have automated displays at bus stops which tell you when the next bus will be arriving. I have seen this in Canada, UK and across South East Asia so I assume it's a thing in many places or is getting there pretty soon.

Secondly, what is the incentive for me to do this? "Check onto a bus" what does this mean? The longest bus trips I take tend to be 20 minutes in length...why would I spend 1/20th of that time fiddling about with my phone "checking in" - there is no user benefit.

While not every idea is about money, I see no way for this to even sustain itself. In the era of self driving cars, smart cities etc. etc. having people to manual data analysis should be reserved only for cases where it is impossible to get a machine to do this...and you will have to pay people to do it - they won't do it for free (unless you can give them something in return...)

Keep the idea machine rumbling though!
