BMW has a few talks from 2017 talking about them and the 
remaining car manufacturers finally moving away from C into C++11 
(on a 2nd talk they refer C++14).

They are also taking care that car electronic standard 
certifications move to C++.

Sony did a similar one regarding embedded electronics.

CodePlay just started a similar work for MISRA.

So with those companies only now leaving C and moving into C++, 
it will take at least a decade before they consider something 
else.

And lets not forget Arduino, ESP286 and ESP32 are making wonders 
for the kids to jump into C++ as their first language.
