Amazon does this with everyone, but even more predominantly in the consumer market.

They'll try and charge you $30 to ship a single product in 3-5 days, but charge $12/mo for prime which ships in 2-3 days, or even next day.
The people in the warehouses are packing boxes. The prime truck is rolling down my street daily.
They could charge you $12 to ship a single product in 3 days, but no -- double the cost.

For both Amazon and MS, the people, the servers, the infrastructure -- it's all mostly in place anyway in a similar way.

Amazon is pulling a China by trying to capitalize on a market to monopolize it. This is not good for anyone.

.. we obey the laws of thermodynamics!

Considering I wrote the CAN interface for an OEM; Yes, Anything can talk to anything else... BUT...
    That's why there's an interface which will only allow you to send data you're meant to send.

  They also point out two vehicles with the SAME available lineup of head units and identical CAN architecture, then claim they're both the most and least secure vehicles.

  Will one of my interfaces ever talk to a brake module? No, Not without a nasty firmware hack. So no, your radio won't be talking to your brakes, or engine. Sorry.

I work at an OEM... I know for a fact The Dodge Viper and the Jeep Cherokee share the same line-up of head units and the CAN architecture is identical.

  How are they both the most and least secure?

  (Also, the Radio can't talk to the brakes, as much as they'd like you to think - I'd know, because I wrote the code for the interface that talks on the CAN network.)

Last time I went to the pizza house I had hair in both dishes that were served to me. There's either a wookie in the kitchen or I'm going bald. (either possible.)

I live in Ontario Canada. Gas here is anywhere between $4.30-4.75 a US GALLON, in CANADIAN DOLLARS (worth less than US Dollars).
Meanwhile, when I'm in the USA, I can get gas for anywhere in the $3.xx a gallon range.
It physically hurts to see people line up here for $4.10/US GAL gasoline. It hasn't increased public transit usage - after all, this IS North America, not Europe.

Raising prices (via tax) to give to the people (politicians) who can't spend the money properly is a BAD IDEA anyway.
It's like giving drugs to a drug addict. They'll just abuse it.

  Why don't you give incentives to the private sector -- Tax breaks on new cars where MPG meets a certain requirement? Gas guzzling cars would soon be off the market entirely as car makers would opt to make more efficient cars, as a profit margin on them would be greater due to lower taxes.
