Dashcam thinking

I'm weird, but this the sort of journey I go on after someone suggested I should get a dashcam for my car. And I end up getting confused about the world. 

First, I don't have time or inclination to know anything about Dashcam's, so I search for Brands I trust to see what models they make. 

A Sony or Samsung or LG should provide all the reassurance I need that I'm not buying something crap. But none of those brands make them....nor do optics brands like Canon or Panasonic, or accessory brands like Anker or Belkin, or innovative brands like Huawei or DJI, for some reason Dashcams are a $5bn business nobody bothers with.

--

Second, I don't trust ANY of those "Dashcam world " blogs, or Wired reviews or any videos, or any such because clearly they are compromised, so I research and it hits me I've never seen and ad in my life for a Dashcam, and thus have no idea what these brands are, Viofo, Vantrue, REDTIGER, DDPAI, so THREE ....how come the biggest brands in Dashcams are so, awfully named

--

Four, I look into features and they are all the same, I realize that the only thing I really care about is that it's incredibly easy to wire up, because it's gonna be very annoying having a lead across my dashboard or a trip to some installer to damage my car..... So we've somehow got 1500 types of dashcam, all basically the same. None are white, none are funky, none have a simple naming protocol,they are the same.

Five, it turns out nobody has bothered to invent a dashcam that's rechargeable. It seems to me that you'd easily be able to make one that works for 1 hour a day and you recharge once per week.

Six, then I dawns on me, you could actually make a really good baby / dog monitor and dashcam combo, you could plug it in and use it as one, charge it up, and use it as the other. Why has nobody made this?

By this point, 34 mins in I'm getting bored of dash cams, so SEVEN I'm wondering how much money I will save on my insurance by getting one.

And it turns out, absolutely none, it turns out no insurance policy in the entire world gives a crap!!. There are no insurance companies that offer discounts to have one, there are no insurance policies who subsidize them, in a world of identical policies, and billions spent on advertising, why doesn't one auto insurer get a bit stuck in and decide to be the "modern one" and offer free dashcams???

--

And then I get even more grumpy, here I am with a Lucid, about to ruin the sleek lines of a car that already has 14 cameras in it. How did they manage to put 14 cameras in it, and not think to have a record function???

In fact, why is it that almost no cars on the road today, offer a in built dashcam, why is it not like a big thing? ( outside of Teslas) , 

What is going on with the world?

We spend all day long spanking billions up the wall on parity products, why don't we just make something a bit better?

I'm not grumpy, I'm just imaginative.

Why can't we make better things? Different things? New things?
