Re: Time lapse of highwat crash in Iowa

I have no idea whether they were planning the escape, but some did manage it. It's still a useful habit to practice (IMO) whether they planned to do so or not. I realised that I didn't explain simply: were they steering away (from collision) or toward (safety)? The result might be the same, but cou...

Re: Time lapse of highwat crash in Iowa

In those conditions, it's often about being aware of (and using) an escape route; which to be fair, some of them did.

Re: Safety systems are there to be gamed...

It shouldn't be too difficult to think up a scenario for an impending collision where the autonomous car you are travelling in will sacrifice your life (or at least seriously injure you) rather than taking evasive action that would/could maim or kill others. Can you come up with one? Approaching a ...

Re: Safety systems are there to be gamed...

We know how fast pedestrians can move sideways (it's not an infinite speed) and have automatic cars moderate their speed when passing humans at that distance, such that any impact will not do significant harm (another calculable limit that we can stay well below). This is likely to mean that vehicl...

Re: Pros and cons of hi-vis

There's a clear progression, for example the typical 'SMIDSY' situation: Driver arrives at junction . . . 1 Doesn't look 2 Looks, but rider is obscured (eg car door pillar, street furniture, other vehicle) [ie 'not visible'] 3 Looks, but doesn't notice the rider 4 Looks, notices the rider, but make...
