Worth keeping an eye on as a simple proxy for consumer interest... (measures popularity of given search terms). "Tesla Model S" currently trending up sharply. As is "Tesla Model X". As is "TSLA". And it's August. People are supposed to have better things to do! (also, the Aug numbers are based on just 3 weeks of search enquiries...) You can also search for individual countries. eg. there's been talk that reservations in some countries, like Germany, have been low. Based on this graph, that might be about to change.
