I don't understand. 104.7 FM is a part of the spectrum allocated for radio broadcast. Why was that interfering with keyless entry systems? Is this just an issue of too much power?

Such pirate transmitters are typically built as cheap as possible. Such things as filtering carrier harmonics don't tend to feature in the design. Pirates with two brain cells to rub together tend to assume that their hardware will be quickly found and confiscated. Thus are more likely to spend money on having multiple "hot spare" transmitters than having one half decent one.

Radio transmitters tend to be pretty good on emitted frequency.. The things that are cheaply made are cars. I'd bet the filter on the door lock receiver is not blocking enough of the radio signal to prevent interference. Keyless entry is in the 300-400 MHz range so only 3-4 times the frequency.

The Acela cost ~$2B and generates $500M/year in revenue. Its been running since 1999 and is successful because it has downtown terminals in Boston, New York and Washington. Also because it runs on existing right-of-way with some track upgrades. Business class New York to Boston is $107 and takes 4 hours which is about the same time as air travel + 2 airport shuttles + groping. So if you choose the right location, it works. However, nothing I've seen about the California plan suggests they are choosing the right location.

Automobile and air travel are subsidized with public money to build roads and provide air traffic services (and security). The only significant public money going to railroads is to build crossings for car traffic. If politicians were looking for fuel efficiency and cost savings instead of the flashiest most vote-getting programs they would be investing in rail.
