Ever wondered why Teslas – and a growing number of new cars – don’t have spare tires? 'Ready whip' is one dubious solution that manufacturers provide.

Tesla often introduces new products with a “Launch Edition,” which typically features unique upgrades and options exclusive to the first 1,000 or so vehicles off the production line. The new Model Y’s Launch Edition costs $59,990, which is $4,000 more than a similarly equipped Long Range All-Wheel Drive model.
