as for "I often forget to lock the doors"... why do you often forget to lock the doors?
Luckily the other car will at least notify me if I leave it unlocked and can lock it through my phone. Would be nice if it just also auto-locked.
Only if you're like right next to the car. I prefer to remote start my car when I'm more than a few minute walk away from it so it actually has a chance to warm up or cool down. Starting it ten seconds before I get to the car is practically worthless.
i'm in legit cold canada and being able to open my garage remotely and start my car means it's a lot easier to herd small kids into a warm, comfy carseat.
It's effective law enforcement that removes such people from society, and renders your neighborhood safe.
You can never have 100% perfect physical safety.
And reaching near-perfect physical safety requires that the state becomes extremely authoritarian.
You instead want good physical safety and effective law enforcement, and then you add on other mitigations for when those fail. "Defense in depth" - locks for your doors, anti-theft features for your car, firearms for your home.
And even the deterrence of a locked door helps cut down on some crime. People are less willing to rob a car if it means (or even they just think it means) getting cut and bleeding, or getting caught on video.
Let's say you're not at home, well, (1) neither is your car and/or (2) it's still unlocked for however long it took you to remember.
Most new cars automatically lock the doors when you walk away from them anyway.
I'm just not seeing the benefit here.
Remote start is huge where I live. When it's -10C and there's a foot of snow you have to dig out in the morning, you can start your car from the app and then start shovelling. The alternative is a hokey pokey of shovelling yourself a path to the car, getting in, starting it, getting out, resuming shovelling. Not the end of the world but it's very nice. Even if there's no snow it's nice to get the cabin above freezing while you're eating breakfast.
