I am pretty sure self-driving vehicles are here to stay, in the near future it will be the main form of transportation soon after that at best the manually driving a car will be only be for enthusiasts and hobbyists (and sport) or at worst they will be illegal, let's hope for the former.
Of course when driver-less vehicles start getting widely adopted all those people who where driving for a living will be out of work and without a big change in how our economic system works well let's say it won't be pretty...
Another issue I have is, how easy can these things can be hacked ? I don't follow the development of self-driving cars closely but it doesn't seem like the companies care about this problem much and imo they should care and built them from the ground up to be resilient to hacking.
And lastly another concern of mine is, will we own the car or it will be "licensed" to us or be "public" and all our data that get collected by it will be available to be sold and be exploited..?
you bring up a lot of really good points. IoT (Internet of Things) development and security will play a HUGE part in making this a safe and secure environment. think of it, we already have devices that know everything about us that we walk around with 24/7, and devices like Alexa or Google Home are starting to become more normal in households. The more things are connected, the more secure the firewalls need to be! Especially when it comes to self driving cars since its also a huge safety issue and could be life or death.
