I think by the time we actually have level 3 or 4 driverless cars the seniors of that time will have no trouble embracing their use. That won't be during my lifetime.

As someone in their 50s I actually have no real desire to drive anymore. I'd be more than willing to have someone else drive me about (autonomous vehicle) when needed and not even have a car. The Internet (online shopping) has really taken a large bite out of my driving needs already. To the point that if I can order it online I will do so over driving to a store to purchase a product.

If we can further enhance online shopping, coupled with advances in driverless vehicles, we should see a great reduction in vehicle traffic in the years to come.
