What is the biggest cause of road accidents in the UK?

There is only one category of contributory factor that specifically
mentions cyclist action, which is cyclist entering road from pavement.
That caused 684 RTCs, of which 8 were fatal (probably for the cyclist).

Â*and there may be a split of other contributory factors by road user type.


There are several categories that say driver/rider, which will cover
just about everybody. I was simply pointing out that cyclists are not
specifically identified in the categories. However, as failure to look
properly is far and away the biggest single factor of all, there is a
fair chance that is the one they also commit most often.

Did you need clean underpants?

Meanwhile, you still free to go about with a clear conscience because
the law allows 2 pedestrians a day to be sacrificed for the beneft of
the economy.

Gawd... you're getting desperate now, aren't you?

So I am thinking could it be that when autonomous vehicles are allowed on
roads that accidents reduce? After all people are not tested anywhere near
as much as the software is going to be in an auto drive car and of course
you can tweak the car, but very unlikely to be able to do that with a
person.

Secondly one of the most common things is accidents with two wheeled
vehicles and pedestrians usually where there are misguided shared spaces or
where otherwise segregated streams have to mix at junctions etc.
Obviously on many higher speed roads its inexperience, on how to drive to
the conditions, ie fog, ice snow and heavy rain.
This is due to the cocoon effect, ie a person driving at speed feels safe
as the acceleration masks the speed and the time needed to stop a moving
mass.

How interesting.

What does it have to do with cycling?

Totally agree with all that you said, brian.

Only thing I'd add is , innatention, like talking on a
phone(hopefully that at least is set on hands free), also looking at a
Sat Nav instaed of just listening etc.

And it is impossible to predict what the cyclist or pedestrians will do.

And one of the 'benefits' of autonomous vehicles is smaller gaps.

An autonomous car should be able to eliminate the errors of driver
failed to look properly (a contributory factor in 38% of reported
accidents in 2018) and, to a great extent, failed to judge other
person's path or speed (20%). It won't be careless, reckless or in a
hurry (15%). It won't drive aggressively (4%) or be nervous, uncertain
or in a panic (2%). It can't be impaired by alcohol (5%), drugs (2%) or
fatigue (2%). It won't fall ill (2%) or be distracted (3% in vehicle 1%
outside). It won't exceed the speed limit (5%) although it could
conceivably still drive too fast for the conditions (6%).

Note: these are not mutually exclusive. There can be up to six different
factors attributed to one accident, so the anticipated reduction won't
be the sum of the percentages, but it should still be fairly high.

If it can do better than a 17 year old in the driving test, the job is
done...

Software has the same telepathic ability as a human. None. Response only
works from an ability to observe actions that are in the process of
being played out.

Obviously on many higher speed roads its inexperience, on how to
drive to the conditions, ie fog, ice snow and heavy rain.

I expect designers have realised that suitable gaps change according to
conditions.
