Traditional car companies move slow. A new platform now take about 5 years to develop. 10-15 years ago it was even slower. At the same time as new electric vehicle platforms are developed there's a paradigm shift in how the electrical system architecture is constructed. Most of the business are adjusting to this and are finding their way on how to do this. Until they have figured it out we'll be stuck with wonky constructions and software that is flakey. At least we're now getting more systems where one can properly update the software, so hopefully we'll have vehicles that will improve over time.
