Author makes several points. I have never understood the whole hoopla around Uber. Contractor issues in Europe (London declared them employees very recently). Driverless that does not pan out. Competitors appearing in several countries. And aerial vehicles are still a big hype. Besides the battery issue, Uber hasn’t thought out the logistics side of aerial transit. I mean an Uber taxi to pick you up and drop you off at a site which is suitable for landing and taking off of those aerial vehicles, after which the whole sequence repeats itself upon arrival, to drop you off at your destination, is needlessly complicated. If you are still thinking of investing in them (IPO reportedly coming soon), then you clearly haven’t done your homework.
