Here’s a thought exercise for today.
A big problem for driverless car engineers is not common easy-to-imagine circumstance such as people suddenly braking on highways, but the random situations we occasionally find ourselves which are intensely human or simply difficult to predict.
It’s the unusual situations where manual override is needed which are going to keep the elderly, the blind, children and the drunk away from Driverless Cars in the short term.
Some situations that are atypical may include:
1. Drive-Through Take-Out – many companies have different set-ups and to program all of them into a car would take a certain level of genius.
2. Buying a parking ticket for an impromptu parking lot (such as for a festival or sporting event) and then parking.
3. Road-works or a traffic accident creating a detour.
4. Police flagging down a car.
Here’s two ideas for over-arching solutions to solve some or all of these problems above:
1. Colored Lighting – Light configurations could be set up that Driverless Cars will recognize and use. These could be installed into McDonald’s at low cost or added into a policeman’s baton. While there’s potential for people to create their own lighting configurations and steer the cars all over the road (for a funny Youtube video, for example) this issue could potentially be overcome by using highly specific light frequencies which are banned from common sale. Alternatively, simple hand signals could be developed to be used in these ad-hoc situations.
2. Telemetry – Taco Bell could easily use a system like a next-generation Bluetooth or Wifi to communicate with cars that have come into their commercial spaces and then direct them through. This could also be employed in all predictable ad-hoc situations like road-works or sporting events but not so much in the case of unexpected events!
The big issue I foresee with either of the ideas above is that of consent. Would an external system need to ask for the driver’s consent in order to then direct its flow? You would say the answer to this question would have to be “yes.” Yet how reliable is a drunk person going to be in giving consent? How about a blind person – how would they know what is going on? Or even someone who has a mental disability?
Due to the issues above it could be a while before the full transition takes place.
