My understanding is that the new blades produce better lift, allowing them to be just as effective at a lower RPM. If you put them on an OG Mavic you might get slightly different sound and better battery life, but you probably won’t get much of a noticeable reduction in sound, since the old ESCs will still at the original rate.
I double checked with them, and they assured me Roku is coming, despite not being mentioned in the blog. Not sure why they left it out.
They do the same thing for cars. They can see your license plate and find out who you are and what if any record you have. Covering up your license plate is a crime.
They don’t use software to track your position, direction, and speed, or to find the operator. But that’s because cars require the operator to be in the vehicle, and authorities can use their eyes, and radar guns, and cameras, to track things like your how/where you are driving and how fast you’re going.
When they showed me the process the courier had to actively swipe to re-lock after closing the door and get a confirmation that it worked. I think they are making it more complex on purpose, hoping to avoid situations like the on you describe.
Here, let me cool things off.

Interesting question. The answer is, we don’t know yet. Autonomous cars are still pretty rare, so the situation hasn’t come up. But people have worried about this.

A couple thoughts – if we use Velodyne’s LIDAR as an example, they will scan each point in 360 degree field of view between 300-900 times a second. So even if a couple of those instances are marred by interference from another laser, the majority of the data would not be.
Second, LIDAR systems typically work in concert with radars and cameras to decide what is happening on the road. The goal is to have the systems support one another, so that if the LIDAR fails at some point, the higher order system making the driving decisions will have other data it can use to deconflict.
I rode this on bike lanes all over NYC and never had an issue. Aside from one angry guy on the Brooklyn Bridge, most people were curious and amused.
Its top speed and handling make it perfectly safe in the bike lane. There are tons of folks making deliveries on actual bicycles with motors tacked on going more than twice as fast as the URB-E can.
