Military couldn't buy Boston Dynamics robots because they were too noisy to use in battle

It's true if you want to haul over 300 pounds of gear on any 4 legged robot in order to do this you are going to have to have a gasoline or diesel engine to provide enough power to do this in an autonomous way. And, smaller gasoline or diesel Hybrid robots which use the engine to generate their electricity for operating and of necessity noisy because smaller engines if you muffle them very much aren't efficient. Only larger engines can be muffled that much and still keep their power and effectiveness. (which is why cars can be relatively quiet even if they are hybrids while their gasoline or diesel engine is running to generate electricity. 

I recently bought a new car for driving up to Lake Louise with my wife.

For example, recently our car emailed and texted us to tell us that it needed windshield washer fluid which I found interesting. However, having a car this automatic and interdependent with humans is it is hard to get used to on some levels too. The other thing I had difficulty at first with is learning to drive with a Fob instead of a set of keys.

I suppose the advantage of driving with a fob is that as long as you keep this in your pocket you are okay. But, if you set your fob in an ash tray or cup holder this is almost always a problem for you if you get out and the car locks itself. Because unless you have another fob you are locked out of your car.

One of the advantages of a fob is that when you want to get into your car when you have a fob in your pocket the door automatically unlocks as you reach for your door handle on the driver's side. The down  side of a fob I find in this car is that you have to start the car up in order to even open the electric windows which I find is sort of a pain in the rear end especially if I'm sitting in the passenger seat if my wife is driving and she gets out and it's hot out it means I have to get out of the car, got to the driver's side, put my foot on the brake before I push the start button in order to put down any windows in the car even if it is above 100 degrees outside wherever we are on earth.

The other problem might be that cars are so quiet these days that you can get out of your car or hybrid or other vehicle and not know it's still running. So, I've learned now to look at the dashboard because usually if the car is off (not running) the dashboard usually goes out on most car too (all the lights). This seems to be the only way to be sure you have turned off the power (gas or electric to your vehicle), especially if it is an all electric vehicle or hybrid.
