Future speed limits Printer Friendly Version
People speed, we all do it but we know its wrong. Every act we take in life has consequences and we shouldn't get away with speeding.
When you purchase a vehicle you have to give your credit card information just like when you register a new phone. Newer cars all come with GPS that can calculate your exact speed. If you decide to speed you are automatically charged 1 cent / second times KM/h over the limit you are. For example if you are driving 10Km/h over the limit you are charged 10cents /second. $6/min.
Cuts cost to tax payers in the form of additional police officers needed and radar equipment / definitely safer / could reduce accidents? In emergency situations where you need to speed (should be never) you will automatically accept the additional cost.
I thought of this when thinking about the future of autonomous vehicles that will eventually drive us around and this type of thing won't be necessary. However, while autonomous vehicles will be automatically going the speed limit, people who do not wish to adopt this technology will continue to drive above the speed limit, putting everyone else in danger. This type of penalty could positively influence these people to adopt autonomous technology if its not made mandatory in the first place.
What do you think? I understand there would be colossal cost to implement this but I am thinking 10 -20 years down the road (pun) when technology has progressed.

Automatic pothole reporting Printer Friendly Version
These days high end cars have GPS, dashcams/reversing cameras and SIM cards (cellular connectivity). (In the UK at least) there are websites where you can report pothole locations, so that the authorities can direct their road repair teams.
Now, with nothing more than a sensor on the car's suspension and some control module, the car should be able to detect when it hits a pothole. When this happens, the GPS location is noted, a suitable still frame from the dashcam or reversing camera video feed is retrieved, this gets overlaid with a mark indicating where the pothole should be seen (calculated from the camera angle, car speed, distance traveled and steering angle). Also, the car's compass bearing is recorded. All of this gets submitted to the appropriate pothole reporting website.
Perhaps, to avoid overwhelming the local authority's websites, each motor manufacturer should collate the reports, and only submit to the website when a certain number of hits are reported.
While this has merit in all vehicles, it may be more desirable in self-driving cars where the driver is less likely to pay attention to the exact location of the pothole.
Reward: As this idea is unlikely to make money for motor manufacturers, it would be somewhat cheeky to ask for the first car fitted with such a system. So, just be generous!
