Project your own bike lanes

things like laserpointers on the sides of bicyles would project two parallel lines = on either side of the bike. This would look like a bike lane to cars, so they would stay an extra foot further away, reducing the risks of bicycling

A bicycle could have something like two laserpointers on it that projected two parallel lines ===== on either side of the bicycle. Visible to cars, this would provide a suggested zone of courtesy in a familiar bicycle-lane form.

Just like self-driving cars it is possible computers could scan traffic and construct optimal sizes of lane width or even cause it to be different colors. The computer would know what to do when there were multiple bicycles near each other.

To get the most optimal angle for the cars to see it, the laserpointers might be at a glancing angle near the base of the bicycle.

Bike Light Creates ‘Laser Lanes’ On Dark Streets https://gearjunkie....r-bike-light-review
This article mentions four products which project laser light as lanes for night cyclists: NiteRider, XFIRE, Revolights, Blaze [xaviergisz, Jul 16 2019]

       Best idea you've had here.

       This will give drivers an optimum aiming point [+]

       Ooh! and a chargeable capacitor with a proximity sensor to make the switch from light to heat laser when a vehicle gets a little too close for comfort.   

       Great idea. I can't believe no-one has thought of this before. If only there was anything on YouTube that gave some hint about whether it would be practical.

       Solid state laser line generators are Baked and WKTE, so eminently practical to implement - powerful enough to be seen even in bright daylight.

       You might need micro stabilizers from making the lines too chaotic to really be called lines, but yep, it's good.
If this gets baked and saves even one life you're a hero [beanster].
  

       Baked. Maybe not well known to exist, but these have been around for ages.

       Yea, this is a neat idea, but it's baked, wrapped for delivery, shipped, signed for, eaten, digested, flushed and currently in the ocean sitting on some poor flounder's head.   

       I has a similar idea years ago and had to cry myself to sleep after my dreams of being a parallel laser light bike lane thingy mogul were dashed.

       Looks baked all right......bye bye idea....
xenzag, Jul 17 2019
  

       Shoot beanie, I bunned it anyway. I really liked it. Oh well, back to the drawing board.
blissmiss, Jul 17 2019
  

       I never thought to check and I'm not sure why...
Normally my gut screams "Nope! gotta be baked."
but nothing this time... like not even a gurgle... nada.
  

       I must think on this.   

       You've got to check before posting [beanangel].
Next one'll be the charm.
  

       Thanks for letting me know it already exists, Oops!   

       I am glad to know it is already available though.
