I don't think GM spent $1BN to buy Cruise. That's might be GM's total spending on autonomous vehicles, including the Cadillac/CMU effort and the Delphi work.

I'm surprised GM bought them. Cruise is basically lane keeping plus smart cruise control, with extra hype. Their driving record isn't very good.[1]
