Give 25B to Detroit
Rather than loaning 25B to a group of companies that will have trouble paying and still leave them weak and ineffective. Take the approach of giving them 25B to keep in business for another year. Allocate 5B for 10 Years to split research with them for next generation cars. And force 40 MPG in 10 years. Maybe they will not survive to the end but at least the country's energy efficiency will improve.
