Tesla Model S uses a proximity sensor to detect the key fob in your pocket and extend the door handle with a motor:
To quote from an article:
"From the instant you walk up to the Tesla S and the door handles motor out of the door, you know this isn't going to be like any other car you've ever driven. You open the door and the air conditioner has fired up, and your music is already playing. You put your foot on the brake, shift into gear, and you are off and running. There is no âoestartâ button. When you arrive, you just get out of the car; it turns itself off and locks up as you leave."
Tesla originally had a sleep mode for the inboard computer that was supposed to consume around 1%/day. But they found that the sleep mode often resulted in the car not detecting the key fob. So they disabled it until they could patch it. Not surprisingly, it sucks a lot of power while its sitting in non-sleep mode waiting for someone to walk by with the right key fob. If they had stuck with a manual door handle and a push start button for the engine, then the idle power issue would never have come up. In any case, Tesla is working on it and will resolved it eventually.

I was in the same shoes after my web host (for several years) got their server hacked by some script kiddies. When I ran a security scan (using Acutenix) I found that pretty much all the server software was out of date: Apache, MySQL, Php, etc. I sent a report outlining the results of the scan to the web host, and they told me that they would "investigate". Needless to say I started looking for another host immediately, and settled for HostGator. They passed several of my requirements:
1) Security: A scan showed that the server was up to date, patches had applied, no serious vulnerabilities, etc.
2) Customer Service: Friendly, helpful and available after hours.
3) Price: Very cheap for shared hosting. The higher tier, such as VPS, were also very reasonably priced
4) Bandwidth & Storage: They advertise unlimited, which I've always been wary of, but their CEO posted an explanation for marketing unlimited which I found reasonable. After several months with around 100GB of traffic, I've run into no problems. The only real limitation they claim is limiting you to the number of files to around 250K.
5) Reliability: They advertise a SLA of 99.9% which is still a couple of hours every year, but I haven't run into any downtime yet in the few months I've used them.
I agree, it has more to do with the nature of the job making IT people arrogant asses. If you are working in IT for a mid-sized company, you are probably coming in contact with a lot more people than in most other professions. Most of these people are faceless, being either behind a phone or an email, so they appear less like actual people and more like "users". These users exhibit all multitudes of behavior, from embarrassed & apologetic to rude & impatient. They are solely calling you to do something for them, while expecting to give nothing back, other than maybe a quick 'thanks, you are teh bomb, blah blah'. Sometimes they ask you to do something trivial, or something impossible (with your limited resources and time).
Frankly these users are technically less competent than you. They are usually clueless to the effort involved in carrying out the requested task, and completely oblivious of time constraints that you may have due to other job responsibilities/tasks. You may perform a minor miracle and no one will understand why it was a miracle. For every stupid question you answer, you are asked a dozen more stupid questions. No amount of hand holding will ever make the "users" any smarter. Even the most affable-natured IT person is worn thin by the constant barrage of requests, especially ones coming from irate users. In the end, you learn that no amount of effort is ever going to make the users happy, so you learn to adapt. You get of your ass and only make an effort when the requests comes from the big bosses or those that you report to. For all other users you adopt a policy of minimal support. If it is not an emergency, you find a way so you do the least amount of work. The longer you are at the job, the better you become at this. And so you become an arrogant ass (in the eyes of the users).
So how to get IT people to work for you? You can get the big bosses to light a fire under their ass, and they will work for you, admittedly grudgingly. Or you can find a way to differentiate yourself from the other faceless users. Be extra nice, let them know that you are a real person by showing your face. Always thank them, and let them know that you value their time, even if you think its their job to be helping you. Of course you may do all this and get nowhere. In that case go back to tip #1.
And yes, I've done my bit in IT.
