Nigel, initially, I simply tried to offer some helpful documentation and a reference link, without offering any opinion of my own to try to provide some information in answer your question, "Are supercaps proven to last longer than batteries at high temperature?" The general consensus from knowledgeable authorities seems to be that this is so. This must also be why Maxwell states, as I quoted already above, "Ultracapacitors will outlast most other electronic components in any given application (in the most demanding environments)". While I agree that the specs do state what you say, you seem to be completely ignoring the wording also included with those specifications that says, "(held continuously at Rated Voltage and Maximum Operating Temperature)" This is highly unlikely to be the case in our intended use of these capacitors and is why I said, "In actual real world conditions in a vehicle". Ultimately I don't know the answer. Dash cams, especially with super-capacitors are a relatively new product category and over time we will all learn from our collective experience more than from spec sheets with theoretical figures and extrapolations.
You know Nigel, as seems to be so often the case in your responses to me and to others here on DCT you have a tendency to turn these discussions into some sort of pissing match over who is the bigger know-it-all. Generally speaking, most folks here have a history of relating in a positive, support manner, sharing information and expertise, learning from one another, agreeing or disagreeing as the case may be in a good natured way, all the while leaving their egos at the door. You should consider trying it.
