Talking with the Australian journal Drive, R&D engineer Stella Clarke means that color-changing vehicles are coming. When requested whether or not “three to 5 years” is possible to deliver E Ink to road-going vehicles, she mentioned “sure.” Nonetheless, it’ll be pricey at first and certain restricted to sure areas:
“The reality is it’s in all probability not going to be essentially the most price-effective factor to start with, so I might think about it beginning off in a selective market after which hopefully broadening out.”
