A version of this article first appeared in Streetsblog. Elders are being left out of the new mobility revolution — and if we don’t learn from the failures of the rise of e-taxis, the transportation challenges of older Americans will only compound with the rise of autonomous vehicles, a new study argues. A coalition of researchers developed a framework to help transportation providers proactively address the under-discussed barriers that aging Americans face when they attempt to use new mobility services like e-taxis, shared scooters, and bikeshare. But the study’s authors say that there’s even more work to do when it comes to preparing America for the rise of driverless cars — which they say could happen fast, whether we like it or not.
