Exactly what the CAVs of the future will look like is very much still up for debate. 

It remains unclear whether form will lead function or the other way round. 

Some suggest that designers have an opportunity to shape how self-driving are used by their non-driving passengers. 

Others will argue that CAV design will be informed by what the vehicles are used for. 

There are some people who believe the introduction of CAVs will lower rates of car ownership and they say that, as a result, it’ll matter less and less what cars look like. 

Others meanwhile argue that people use transport as a way to express their identity, and so it follows that CAVs will have their own design hierarchies – just as cars, coaches, and planes do today. 

In fact, of all the tricky topics we’ve tackled in this series, it’s fair to say that the design of connected and autonomous vehicles is the one where there’s least agreement. 

But that won’t stop us from trying to find some kind of consensus!

It’s July 2015, and Andy Greenberg is driving his Jeep Cherokee through downtown St Louis.

The weather is normal for a summer’s day in Missouri: clear and warm. So Andy finds it a bit frustrating when the windshield wipers start up. Especially as he can’t seem to switch them off.

Then the air conditioning turns up full blast, even though Andy hasn’t touched the controls. Next, the radio switches on, playing music at maximum volume. Andy presses the button to turn it off, but it keeps going.

At this stage, it’s pretty clear what’s happening. Andy’s car has been hacked.

But what might such an attack look like in 2019, conducted on a driverless vehicle? That's the question we're asking in this month's episode of Journey Makers. Welcome aboard.
