Self Driving car
selinz   5/10/2014 11:41:50 PM
I recently encountered a google self driving car with two passengers, one in the drivers seat of course. It took all the self control I could muster to not get in front of it and slam on my brakes!  I do wonder how well it would do. I would think that it should be possible to respond faster than a person. However, would the Google car recognize the devious look on my face as I pulled in front of it?

Self Driving Car - Driver's Test

I'd love to know how a self driving car performs from the viewpoint of a Registry of Motor Vehicles driver's license tester. If the route were mapped out in advance, what comments and grade would the instructor give and why? If a human pretended to be driving, how would the instructor grade them?

My concern isn't so much with the self driving car just off the assembly line, but what about 6 months plus down the road when a sensor fails in such a way that the system cannot detect it?  Let's face it, when something as simple as an ignition switch, floor mat or gas pedal can cause a failure and recall, what makes anyone think that a self driving car will not need a weekly or at least monthly inspection?

My worry is that my car at the present moment nags me about all the thnigs I have done or not done.

With the self driving car I can see the point at which the on board computer says in a Hall like voice "I have decide that you no longer desreve me" and pushes me out the door at the legal speed limit.

Will the self drive car be suitable for driver training? Police persuit? Villans?

As a caravan tower, will the self drive car be able to compensate for a trailer twice the length of the car?

It's going to be an interesting ride.

Hi Crusty.  The old saying applies.....

To err is human

To really stuff things up takes a computer......

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
