BMW and Mercedes call it quits on their self-driving car partnership

After less than a year, BMW and Mercedes are ending what was supposed to be an ongoing partnership to develop automated driving technology. The two automakers described the split as "mutual and amicable." They were also quick to note they may renew the partnership in the future. A handful of factors led to the decision. In a joint statement, the two companies said developing a shared autonomous vehicle platform was a more complex and expensive task than they had anticipated.
