Most modern electronics do not like voltage surges, so it's cheap insurance to make sure the connections can't come loose. I think it's also possible to blow the ECU and/or the alternator diodes in most cars if you connect jumper cables backwards! We tried to do a lot of Murphy-proofing in the aerospace business, but there is a practical limit to that because there are so many ingenious idiots in this world!
