I will only assume that crossing the road is not a huge problem for blind people. I am sure most know how to do it safely, traffic light sounds or simply asking someone to help. I doubt anyone would rely on internet/videochat for something as high precision as that.

I don't know anyone blind, so I might be wrong on some part(s).

Crossing the road is definitely stretching it! We are adapting the website to reflect that. We are already getting a lot of feedback with interesting use cases – it's is going to be really interesting to see what the community that is building around By My Eyes will come up with!
