Technology / Re: Does regenerative braking have a hazardous complication?
« on: Today at 12:03:38 »I recently spoke to a guy on Twitter who designed side-impact protection for cars, so I asked him if there was any evidence that SIP had saved any lives. He didn't have an answer, and the more I pressed him the more he squirmed.It's relatively easy to assess the damage to occupants caused by a lateral collision, then check the statistics of percentage fatalities normalised by probable impact speed. Intuitively, I doubt that anyone is more tempted to drive into vehicle A rather than B because A has SIP, so a first-order approximation would suffice.
Drug licencing depends on where you are. In the USA it has to be "no worse than" or "significantly cheaper than" an existing product and in the EU it doesn't actually have to work at all, as long as it meets production quality control standards.
