When you say watch do you mean watching on a special devices installed on those transport mediums or in a mobile app? I think the trickiest part or the limitation to the number of ads is the attention period of the users; some users can handle watching several ads in a single trip others can handle only one. I think AI can be handy here.

Still though, generating the traffic to the ad is sufficient enough regardless of the end-user actually watching the ad! 5 per hour or some sort of limitation to stop the abuse would be a good idea though

That's indeed a solid point, distance seems to matter a lot in this project, as the more the distance, the boring the customers and the more likely they will like to go through some stuffs to keep them busy, like reading magazines and possibly going through the app, i believe the team is making considerations on this, as its really necessary to cover every avenue

I don't know how you can predict so easily that the project can arrive the hard cap of the ICO. May I know from where you know that?

I do agree but it is possible to make a lot of trains that booked using the Tachain app in the future so there is no problem on it.

I don't think that the whole market is on decline can bring many opportunities to stop people to invest in the project. This is a good project, isn't it?

5 ads per hour may not be good idea. What if I hired a taxi and my trip complets within 30 mins. Normally within a city a trip won't take an hour

unfortunately, we have to assume that there are always people who exploit a system. I can well imagine that many taxi drivers then have 5 smartphones on the passenger seat :-)

Yes, absolutely the project is going to make the transportation service more  superior for travelling. With the help of this project we can experience safe transportation. So basically the project is every helpful to everyone those travel very often.
