Ageing in the suburbs: a transport disaster waiting to happen?

Here's an interesting reflection from the US about the ageing population in the suburbs. The generation of baby-boomers (now between ages 50 to 68) and older represent 60 percent of the owner-occupied homes in America. Many live in highly car-oriented suburbs. When they will no longer be able to drive, demand for costly public transport services in low-density areas will probably increase and the risk of transport poverty will lurk around the corner. The article proposes some promising solutions to allow baby-boomers to age in place, such as self-driving cars, the sharing economy and redesigning cul-de-sacs as hubs for communal living. 

I'm interested to know if this trend is also present in Europe and how cities plan to face the challenges associated with this prospect?
