Where is the radiator?

Depends on the car. Models 3's face down.
Almost any AM station I'd want to listen to streams online, but that can be tricky to get working. A phone via Bluetooth could probably get that on the car, but that can be a real hassle. There are some stations that switch programming during their streams - especially for pro sports since the leagues (MLB, NFL, NBA) have their own radio streaming services.
But a lot of new ICE cars don't have AM radio any more.

Which ones so i know what to avoid?
Car companies say AM radio signals interfere with the electronics.
Here are a few that have or are eliminating AM, at least on their EVs:
BMW, Porsche, Audi, Volvo, Volkswagen, Tesla.
Regardless, my understanding is this is more prevalent on EVs; far fewer ICE vehicles are affected.
I believe Ford announced their plans to do so, but not sure.
I have Premium Connectivity on our Model 3; that may be necessary to stream AM. $9 per month...

And next it will be FM interferes.... its all about the monthly subscriptions.
If I was camping with an EV and got a power outage I would cancel the trip, like I would cancel my trip if there is a gas outage and I'm driving a gas car with an empty tank there, nor would I camp somewhere with a horse and there's no grass for the horse to eat nearby.

Get used to the future when frequencies are refarmed into something else. Analog TV frequency in the VHF and UHF are already refarmed when we migrated to ATSC and either already or will soon be refarmed into LTE and 5G signals. AM may happen later but FM has the very valuable frequency that would and could be refarmed just like the TV signals (they do overlap).
You can look at it both ways, like teaching a horse and buggy owner how to drive vs telling them to never drive and just keep using horse and buggy. Rental car is a good way to learn how to manage an EV (driving is pretty similar obviously) that you can easily return, instead of buyer remorse afterward.d
If anything they would learn to search for chargers and determine when to stop and which route to go. Horses can often go a very different route than cars and when cars first arrive they have to drive different route (i.e. the long one). Same would be for EV going along major roads with chargers along the way, or an even longer road with even faster chargers, and stay in hotels with chargers, and always plug it in even for just 5 mins if there is a charger and you can't charge it to 80%.
Made in China for an OEM should be great quality unless it is designed wrong. Ultimately it is Tesla's responsibility to design the system correctly.
Many OE build in China using Chinese OEM, Toyota included, and they last 25 years 250k miles. Then we have problematic US, Japanese, European made gaskets and parts designed wrong and they ended up needing recalls and replacement with things like Felpro problem solvers. The buck stops with the manufacturer / designer.
Not to mention Teslas are the most made in America cars.
A "receiver" interfere (not a transmission) with the electronics sounds like an excuse to me. AM radio is already all over the air and if receiving it cause problem they just didn't want to do it because of cost. Most importantly they just realize people don't want to pay extra for it and don't care if you take it away, like cassette player in cars.
Not exactly. There's a saying if you are not the customers you are the products.
FM radios have been garbage replaying the same stuff (paid for by advertisements and promoters) for a long time and guess what. The songs aren't the best (they pick artists who would accept a smaller cut, or songs are cheaper because they are older and not as popular), and the advertisers can't target you from your listening history so the advertisement aren't worth much, so they can't pay more for the better songs and contents. There is a reason now most stations are consolidated to the same owner (I heart Radio?) except a few non profit or public radios relying on donations. Classical probably being the only good one I listen to now, and they often have little royalty to pay.
It is like free school lunch vs buying your own lunch at work, they aren't the same quality.

Tesla is unique in that their factories in China are just as important to them as their factories in the USA. I understand China built Tesla’s are now imported into Canada.
Some more EV common sense that isn't so common.
As far as people thinking China cannot manufacture good components, I have this:
It just doesn't work. Have you driven under power lines while using AM radio? That's what you'd get while driving. I've never done it, but I would be curious to try driving closely while my wife is in the Tesla and see what the AM radio does in my VW.
I guess anything is possible, but it's been known for many years that high current electricity fools with AM signal and FM isn't very sensitive to the same interferences.

Depends upon the geometry of the cell. For cylindrical cells, the issue is that all the surface area is on the sides (radial), but all the heat transfer happens through the ends (axially). So often they try to keep the sides cool, but try to add some thermal removal on the busbars that connect cells.
For pouch cells, there isn’t really a good direction for heat removal, but the sides that have lots of surface area are very large compared to the cell thickness, so cooling fins or pores can be added between cells or cell groups. Of course doing this reduces energy density.
