With 90 minutes of data, they could pick out one driver out of a sample size of 15 . How meaningful is that, really?

Damn man... how many people do you let drive your car?

Only me. And given how buggy-as-all-hell the Ford software is for driver displays/interfaces, I wouldn't let it drive itself either.

I can't see how this is a bad thing at all. Currently rates are set on arbitrary things that merely correlate with driving skill, like past record, age, and gender, etc. I'd love to be rewarded for actually being a good driver. Rather than being lumped in with bad drivers who have a high chance of being in $50k accidents, which everyone has to collectively pay for. Driving is also the leading cause of death of young…

The whole point of insurance is not to lump you into good driver / bad driver categories. If you make bad drivers consistently pay for accidents, then you might as well not have insurance at all, and you'll pay perfectly…

In the US, car insurance gives discounts for all sorts of things and charges bad (really, high risk) drivers more. For example:

The privacy concern is valid. It won't be long before all new cars are sending data from the sensors to third parties, and it would be unthinkable for the manufacturers to ask for your consent before collecting that data since they'll make money off of it. The article mentions concerns with insurance companies. One I worked for tried to get customers to agree to having their rates adjusted based on data from their ca…

What if it turns out that people who take corners faster make fewer claims?

Or what about if the people who take corners.faster make LESS claims?

PS: not trying to defend aggressive driving, I'm not an agresive driver, just saying it'd be interesting if a lot of our assumptions were thrown out the window with that data.

Weight is only one dimensional though, so you'll have more collisions. If two people happen to weigh about the same, then your weight sensor is useless and your driving analysis is not.

It's far from useless, it limits the pool of candidates to two. Far easier to distinguish two drivers from each other than fifteen.

And the article points out that they can already distinguish drivers with 90% accuracy based on the throttle sensor alone after 15 minutes of sampling. With extra sensors or more time, they get much closer to 100%.

So yes, you(s) are all correct. With one sensor you get decent accuracy, with more you get improved accuracy.

Noting that these are forensic assessments, and thus useless for personalising car settings when a new driver gets into the vehicle.

What's the difference between your comment's "LESS" and its parent's "fewer"?

The whole point of insurance is to make you pay for the risks you take, and not for when you get lucky/unlucky.

That we often lump people together is just one implementation of insurance. But not a necessary feature. Otherwise, there would be no insurance for one-off events---but that happens all the time.

There's nothing inherently 'social' about insurance.

Agreed. A 10% false positive rate is huge. Expand the dataset to millions and I doubt you can identify individuals quite so certainly.

I don't believe the application is in surveillance or tracking. It's just useful to know who is driving out of say a few people so you can adjust vehicle parameters to them.

Modern cars will already learn about driving characteristics so they can better manage the car to match, but I don't know if they try to match individuals.

Obviously, you'd want to use some more (and more useful) features to calculate your price. (Otherwise, your insurance company will lose out to the competition that prices better. You overcharge low-risk drivers who will leave to a cheaper alternative for them, and are left with the high-risk drivers who cost you a lot.)

The area you are driving in is an obvious candidate. Or even the particular roads you are driving on at particular hours.

Geography is already taken into account for insurance rates. Why would that cease to be the case with more information?

I'm surprised it took 90 minutes; I'd imagine that it'd only take two or three. The data is very rich and continuous, and the knowledge is almost entirely reflexive. I would also think that identifying typists wouldn't take much longer. Does anybody know of any papers on that? You could pull that off with javascript.

I don't know of any papers, but for verified certificates from Coursera, you validate your identity via a webcam selfie and typing their one sentence honor code into an input field.
