The newer cars with "leave your fob in your pocket" access are constantly on standby waiting for you to approach the car and touch the handle/press a button to unlock it.
Varies from vehicle design to design. The 12V on the fiat is the same size as the ICE version (likely why it can last a couple weeks), and many EV's WILL tap into the traction battery to top off the 12V.
My neighbor had a brand new 2009 X5 that constantly ran down the battery because of this. BMW's service reps told him this was "normal" and he had to store the key somewhere else in the house farther away from the vehicle. Who knew the BMW comfort access option also helps you get more daily steps in on your Fitbit. Win-win.
VW’s KESSY system is the same way. Having the key too close to the car will keep waking it up, running down the 12 volt battery.
I believe the Gen II Prius has a button you can push to put it to sleep. The Gen III does not, but supposedly goes dormant after a week of inactivity.
This is the most honest writeup on the topic I've seen so far. I think most discussion on autonomous cars has been 90% hype so far. There are significant technological challenges, nevermind the HUGE societal, legal, moral, and ethical challenges required, which I believe will doom autonomous cars. I think it far more likely that more driver-assists will trickle down to luxury cars.
Actually, maybe that's the point all the hype is missing. Maybe we don't need 100% perfect, 100% fully automated driving aids. Just add enough to keep the idiots from doing most idiotic stuff most of the time, and detect when average drivers are distracted. If we just taper off the worst 20% behaviors, overall road safety will go up for us all in a step change.
Isn't this one of the reasons that it has been suggested keeping your keys in a tin can or similar thing while in the house? It blocks the transmissions from the keys to the car.
Except that those who embrace, oppose, or are indifferent to the technology expect it to be 100% perfect, all of the time. When an incident with automated driving does happen, it's big news. The YouTube video gets posted, tweeted, and forwarded everywhere - and the general takeaway is "this isn't ready". If that's the standard that the technology is held to; it never will be ready.
If you're in the habit of stowing your keys somewhere in the house while you're home, that could help.
That covers a pretty big percentage of the population
(and you're right)When a person makes a mistake while driving and causes a crash, the liability starts and usually ends with the driver who made the bonehead move, and their liability insurance doesn't have anyone else to sue. In many cases, you can't get blood out of a stone.
My 2008 BMW 118d has comfort access, and has never, ever not started. Though when I lived super close (2km) from work, it would deactivate comfort access one winter, I guess because of low batery voltage.
Side story, and special precautions. When the battery backup (UPS) was serviced at a place I worked years ago, one of the tools in the technicians tool bag/box, and there had to be two technicians working at a time, was a
I like his videos. GM put out an animation on the Gen 1 Volt transaxle, which was ok, but when he did a teardown on the transaxle, I got exactly how it works. Now, if only he'll do one on the Gen 2 Volt.
You sound like me about six months before I bought my EV
