There's a great deal of consternation in the auto industry presently, but that concern is divided in to two camps. On the one hand, there are those in the here and now anxious about whether total industry volume in the US this year will be 18m or 17.8m. On the other hand, there are those more concerned about the future and whether CASE (connected, autonomous, shared and electrified) or ACES (to put it another way) will fundamentally challenge the industry's business model that's been built up over the last 100 years or so. The differences in approach were there for all to see at the CAR Management Briefing Seminars held in Traverse City, Michigan last week.
