Thinking about driverless cars? Don’t let your license lapse yet

I hate to drive. So I almost hate to share this passage from a recent post from Doug Dawson because I want driverless cars to happen so much – but not badly and it looks like driverless cars happening, especially in rural areas, soon would be bad…

A colleague sent me an article that had been published earlier this year in MachineDesign magazine that predicts that driverless cars can’t be realized until we have a ubiquitous 5G network. When looking for the original article on the web I noticed numerous similar articles like this one in Forbes that have the same opinion.

These articles and other similar articles predict that high-bandwidth, low-latency 5G networks are only a few years away. I’m not quite sure who these folks think will invest the $100 billion or more that would likely be required to build such a wireless network along all of the roads in the country. None of the cellular carriers have such grandiose plans, and if they did their stockholders would likely replace a management team that suggested such an investment.

Doug goes on to outline a number of practical reasons that 5G isn’t there and the investment isn’t likely; ending with…

Network engineers also would advise that for a critical task like driving at high speeds that every vehicle should have a redundant back-up connection, meaning a second wireless connection in case the first one has a problem. Anybody that puts critical tasks on a fiber network invests in such redundancy. Hospitals that use broadband as part of a surgical procedure or a factory that does precision manufacturing will have a second fiber connection to be safe. It’s hard to imagine a redundant connection for a moving car since the only place it can come from is the nearest cell sites that provide the primary connection.

I don’t know how other feel about this, but I’m not about to trust my life to a self-driving car that needs a connection to an external data center to be safe. I know too much about how broadband networks function to believe that 5G networks will somehow always make perfect connections when other fiber networks don’t.
