What do commuters do now while using mass transportation? Read the news, read ads or social media, talk, work. You could say that Microsoft, Facebook, Google, Apple, and Samsung are already big in the “autonomous” section, in that they already provide the information, entertainment and work environment for commuters who do not drive to work.
I think it’s only natural that those companies want to get in on the autonomous car industry, at least for the software side. I’m thinking that it might be more likely that companies who do hardware have a greater interest in it, but so far, from the 3 companies with a hardware side; Samsung mainly, but also Apple and Microsoft, only Apple seems to be putting research into autonomous cars. (I have too little knowledge about Huawei and other Chinese companies to know if they have the same possible reasons or approach)
Perhaps driving to work is mostly an American thing and Samsung and Microsoft see the world going more towards increasing remote work, increasing mass transportation.
It’ll be interesting to see the development. Maybe I will still be alive in 30 years to look back on this comment and see what happened.
