There's a huge profit incentive to upgrading millions of smart phones than a couple of thousand ELRs (and I'm being generous here.) The more capable the phone is, the more apps you'll might purchase to take advantage of the upgraded functionality.
Your observation is a valid concern for not just the ELR, but any Cadillac with software-configurable dash displays and CUE. And just like a smart phone, a well supported software path that adds new functionality to the ELR could help the vehicle be more attractive to the types of tech-savy buyers GM is supposed to be targeting. Sadly, Cadillac has completely missed a terrific opportunity to build excitement into their entire line of vehicles that use software-configurable hardware, and the disappointment echoes from far too many posts on this site. GM would have been better served to have collaborated with a company like Apple to design the driver-vehicle interface, with regular functionality upgrades performed via owners synced Wi-Fi connections at no charge. Happy owners become loyal owners, and loyal owners become word-of-mouth spokesman for the brand.
I would hope a performance-enhancing software upgrade becomes available to the ELR, but if past history is any indicator . . . . don't hold your breath.
Unrealistic pricing and a few disappointing issues aside, the ELR is still a nice vehicle. ELR has so much untapped potential for software-based, user-configurable, customized enhancements. It's a shame that Cadillac seemingly ignores what could really elevate the car (and brand) in the eyes of current owners and potential buyers. Their lack of meaningful communication to the public gives the impression their "vision" comes down to winging it to see what works, rather than Daring Greatly to lead the way.
