I think it's generous to attribute reusable rockets to Musk - the Space Shuttle Columbia went on 17 missions - Musk didn't develop the first reusable rocket.
As for electric cars, I believe the limiting factor was battery technology, which has improved in leaps and bounds in the past decade. Tesla wasn't the only company developing electric cars - Renault-Nissan Alliance achieved the sales milestone of 350,000 all-electric vehicles delivered globally in August 2016, ranking second was Tesla Motors with over 139,000 electric cars sold between 2008 and June 2016. It's also not clear that Musk founded Tesla, but I'm not clear on the history there.
Tesla do have the strongest branding in electric cars though, and I would attribute that to Musk's ability as a showman.
