what's the state of the art of augmented vision and first- or third-party​ safety measures?[0],

I mean, the mods quit Brighton beach (UK ( so I've not seen a excess of rear view mirrors lately. (the used market may still be saturated..)

phones are beacons,
[2]

potentially we could be broadcasting centimetre accurate position and velocity

I like the idea of roadside computing cabinets downloading local trip data and doing the hard lifting but basic stuff like flow scheduling

how about this beacon tells you its stopping distance, driver reaction time, gear and acceleration limits and expectations of driver style?

I am convinced that there's so much more to learn about elementary ergonomics, about human vision not computer vision and about what open the market will pay to attach devices to vehicles that already challenge budgetary constraints for most new purchasers.

I absolutely would pay say $500 device capable of displaying correctly where I am regarding the other road users and their intentions or probable because they're on the work run same as always. for a glance

I don't drive any more, but I would have claimed in my twenties that I drove to work at a incredibly predictable pace. I doubt it could be so smooth with the traffic today, but in suburban and rural areas, well a big pothole at a dirt crossing sure will affect the movement of hazards. Where LIDAR may not travel, "local pilot's license knowledge" I reckon could save a great number of lives. The sudden steering wheel input and deceleration and acceleration around a big pothole would well warn fast coming vehicles to not take that lane as free, if not then used for turning right across a middle lane, so stay on the hard shoulder instead)

I want to glance at the road between my handlebars at a projected map of data,

(only when i am glancing down. The other day I saw the Canon Eos 1-v 35mm film camera linked being discontinued. This and the wonderful Eos 3, had eye focus point tracking. I remember reading the brochures and thinking BS, but nope, I remain convinced that you are going to get better results if you have dark eye colour, not pale blue like mine

my brother is a professor of transport research, whose tutor literally created the formal discipline (kinda Djikstra for transport, but sadly despite his traffic following equations being important, my brother and I should have either subscribed to better peace pipes, or lived when computing wasn't infant and so our interests not so separated. he is a Cambridge alum, I'm just either the commercial enemy or PPE impenetrability, oh i i did my best to not get the green corduroy jacket and lecture physics on Open University... I go on because I know nobody deserving a real professional commercial successful (meaning completed, delivered, used. I honestly think the nearest he came to a product launch was resolving traffic light sequencing in Tokyo in the early eighties, if you wanted to hire genius safe in the certainty should suddenly genius demand credit, the last thing you ate was poisoned, to my bro you go. I think it is because the litany of failure is so incredible. once he started reciting funded closed European programmes and projects. long minutes in, i realised he was reciting alphabetically by the conurbation and chronologically since, well he knows or once did, each and every one.

I couldn't plug my brother enough,

byt my excuse for doing so here, is the fact that I can write books how to get value from him of the order Google was paying for some feted guys tangled up in that uber unpleasantness. The fact may be that cases like that keep my always almost retired brother out of big business. AFAIK his refusal rate is in immeasurable range off p=1. I would drop my life to move that needle and get the world itself a result. (at least I can't imagine deaths in my brother's vision of transportation future) Not would, I guarantee you devotion, as far as the best alignment of a exceptional pitch with what makes a exceptional mind tick that has resisted professional commercial scrutiny for half a century. I would do anything to have him on my board if I was in the field. Not being funny, were the closest in a combined century, but I receive nothing. Silence. Zero... the air itself approaches 0K if i broach commercial transport research. Sure he could be just under NDA. Just NDAs I know displease his academic mind how rattle snakes regard dingoes. But you can take my limitless effort to broach any possibility as my word. Any time. Whilst age permits,be ideal..

this immediately worries me about"throwies" and how much this matters for potential unintended regulation consequences

CANON EYE TRACKING I WISH TO CONTROL ON STREET HUD OF ROAD USERS
A series of tiny infrared LEDs (light emitting diodes) shine harmless infrared energy onto your eyeball as you peer through the viewfinder. Light sensors record the infrared reflecting off your eye and calculate the focus point. A computer in the camera then examines this data and decides which of the focus points is closest to that point and selects it. If the camera is in AI Servo mode then it will also adjust focus automatically based on that selected point.
