Care to cite any evidence of that?

The Ross Ice Shelf is open to the sea on one edge. It is possible to access the same site by going deep under the edge of the self and then in. It is not "sealed away".

Given 1 foot clearance on each side of the vehicle and a vehicle width of 5 feet gives a 3 foot clearance for the pedestrian. It the pedestrian is in the 3 foot area in the middle of the lane there is not enough room to go around. Many accidents are causes when pedestrians panic at seeing the approaching vehicle and stop in the middle of the lane.

You are assuming visibility is perfect at all crosswalks. There are many obstructions such as parked vehicles, telephone poles, other people, etc that obstruct your view of crossing pedestrians. If you add night, rain and/or dark clothing it gets even worse. In one instance I was traveling in the same direction as a pedestrian who was playing with his phone. He turned left into a crosswalk without stopping or even looking. How was I supposed to anticipate that move? Luckily I had time to stop. Had I been ten feet closer we would have hit.

I don't see how you can defend not stopping and looking before entering a crosswalk. Yes, some drivers need to be more attentive but some pedestrians need to be more attentive as well.

Sorry you are off by a factor of 10. Ten time faster rotation means ten times the lift not 100 times.

The more accurate numbers are 100 *.38 = 38. So the rotors would have to rotate 38 times as fast.

Even compensating for gravity difference the air density on mars would be similar to flying on earth at over 35,000ft.

Then there are the times when one is following at 2 seconds, someone changes lanes and slows down in front of them.

Just because one technology has issues has no bearing on whether or not an completely different technology has issues.

As for your "attentive and skilled driver" point, there are times when that is not good enough. For example, I was driving at a 2 second interval behind a van. It made a quick lane change. In front of it was another van. It took me a second to realize that van was not moving. It had no lights showing at all. I nearly hit it A braking asist device would have kicked in immediately when it calculated that I would hit the stationary van.

The pedestrian may have been crossing legally but at a time where the driver could not stop. Say I am driving legal limit of 30 mph down the road. The typical stopping distance is 75ft. What happens if the pedestrian enters the crosswalk when I am less than 75ft away? The pedestrian may have the right of way but the vehicle still could not stop in time.

There was one instance where a police car was approaching with lights an siren flashing. A pedestrian though she could beat the police car by dashing across the crosswalk. She didnt notice the car ther the cruiser was chasing till it hit her.

I have seen too many stupid pedestrian moves. Crosswalks are not magic shields that stop all vehicles. What ever happend to stop and look both ways before crossing? Pedestrian need to take responsibility for their own safety.

I used to always blame the driver for hitting pedestrians until I had a couple of incidents with pedestrian texters.

In on case a pedestrian was waking on the sidewalk going in the same direction I was. He came to a perpendicular crosswalk and just turned left into it. He didn't stop or even look. Had I been ten feet forward I would have hit him.

In another instance I was looking for a parking spot and a girl walked out right in front of me from behind a truck. I stopped less than 2 feet from her. I ended up in line behind her at Starbucks and asked her about the incident. She never even knew I was there.

Another time I was travelling on a dark and rainy night. I was approaching a crosswalk and a person in very dark clothing came out from behind a power pole and strode into the street. I barely stopped.

There are too many pedestrians that are engrossed in their phones or iPods and do not look around. A vehicle can only avoid hitting a pedestrian if there is enough time. While the pedestrian may have the right of way it is always advisable to get eye contact with drivers before entering a crosswalk or intersection. You may be right but but you may also be dead right.

It s possible that those ex-cops are the ones that are pissed off at the bad cops for making them look bad.The more people you report it to the higher chance something will happen. It is very easy to do nothing and then gripe about the incident happening. If you report it and nothing happens at least you tried.

There is one sure way of guaranteeing that internal affairs will never investigate an incident; Don't report it.

Did you report it to any of the following; local police board, state police board, prosecutor in the case? The prosecutor would be your best bet as they usually get pissed off when their witnesses are messed with. The prosecutor could charge the officers with witness tampering. Did you politely ask for the case number so you could refer to the incident later?

So bypass the hard parts by soldering into the circuits and then say the device is insecure. We have no idea how many layers they bypassed. This is like entering the bank, shutting off the alarm with the code, opening the vault door with the combination, drilling a few safety deposit boxes and then saying safety deposit boxes in banks are insecure.

If you need physical access to the dongle it is not a true exploit of the dongle.

There is a light on the current Glass but it is software controlled and can be disabled.

A visible physical shutter that can be moved over the camera lens to prove that one is not recording video. I realize that it does not deal with people not near enough to see the shutter but at least it will put the people at the table at ease. This is not a perfect solution but it might help.

The only difference is that a pill is passive while this method actively embeds objects into the stomach wall.
