In SOMA in San Francisco I'll often hear motorcycles drive by that are so loud they set off car alarms along their path.
And don't get me started on the cost/benefit of car alarms.
As for the cameras, I’ll echo the sentiments of a sibling comment. You don’t want them. I lived in AZ in the mid 00’s when these things were everywhere. They mostly serve to disrupt the natural flow of traffic and caused people to make dangerous sudden stops when they should have proceeded through a yellow lights. Also, many are operated by third parties who take a cut and charge a fee to run them. If they fail to produce enough revenue they become a financial liability to the city, which will either monkey with signal time to increase ticket revenue or simply remove the camera.
To be fair, convertibles are similar. The wind noise of the open air is very loud when moving at speed, so the stereo must be that loud to compensate. There are some setups that will increase/decrease the volume appropriately as the speed changes, but that's not always the case. So as the bike is sitting at a light, the sound is still blaring at the same volume. Maybe the rider is still an asshat for not lowering the volume, but I'd go so far as saying their an asshat for refuting the concept the sound of the ride is the experience by blasting choons.
