Toyota Motor Corp. plans to spend $2.8 billion to make sure its system for writing the software for self-driving cars will be just as efficient as the factories that build them.
The company needs faster and more reliable methods for writing software because self-driving cars require “millions and millions’’ of lines of computer code, according to James Kuffner, who’ll lead the new effort. That compares with tens of thousands of lines of code in cars just a generation ago.
