How can you use VHDL to model a microcontroller such as an Atmel AVR, Microchip PIC, TI MSP430, Freescale S12, etc.?

Even if you can model the rest of a mixed analog and digital circuit the microcontroller becomes a black box that you have to assume works correctly with all the other components.

The hard part is if you use something like a microcontroller. The code being run can be very difficult or impossible to simulate properly if you are doing anything non-trivial with I/O. Yes, you can test each section of hardware separately but in the end you still need to ensure it functions together as a whole.

They do enforce the limits. The issue is that a thousand cars going 75-85 mph will pass the unlucky motorist and police car before the officer is back in position to tag another driver. Police cars looking to tag speeding motorists is also one of the leading causes of traffic jams. Drivers see a cop manning his radar gun during high traffic and the next thing you know there is a traffic jam from people slamming on their brakes to shed 5-15 mph.

Another problem with "privacy policies" is that they disappear when the company does. Barnes and Noble was able to buy the intellectual property of Borders when they went bankrupt. This included all the customer information regardless of the original Borders privacy policy.

So even if you trust a company if it goes out of business your information can go to the highest bidder.

Firmware updates are normally applied to a car via secure communication on the CAN-BUS (via direct connection or cd player). If an update prevents a module from accessing the CAN-BUS it would be easier to swap out the module than to reprogram the module using a different method.

Perhaps the car as a whole wasn't bricked but computer systems on it may have been.

Mostly because every Windows machine has a remote desktop client but almost none have a VNC client installed. I actually do have a UltraVNC server running but since remote desktop is easier to access I have never really used it. Honestly I forgot I even had it.
