Peter Rawlinson should have known better, or hired people that did! Also, IMHO the basic software design seems flawed and I think that it is being re-written which may be why there have not been any recent updates. Again, poor management.
Knowing what I know about software development, I can say if there are serious underlying architectural issues that need resolving (due to say, being rushed into showing off features for the executive team or the marketing team before production, high turnaround in staff, etc.) the correction can take way more time than you might think. What looks good in a demo and what works for end customers are usually two very different things.
That technical debt adds up quick, and it always bites you in the butt at the least convenient time.
Given the wake from sleep delays I've heard discussed here, that may very well be where Lucid is right now. It certainly feels as if there are some fundamentals that aren't quite sitting right.
Some bugs can be fixed in a few seconds. Some take months. And you never know which ones are which until you dig into them. And sometimes you can't even address the user-facing stuff because the foundation is so borked you need to rip out and rewrite a ton of code just to get back to a functioning system.
A lack of regular updates feels like they aren't doing anything, but it could mean they are doing way more work than if there were quick bug fix patches every week. The hope is on the other end of that work you have a system that can then be tweaked and updated cleanly and quickly in the future.
Should it have been "done right the first time"? Sure. But in many years working in this field, I've never seen it. Not because software managers are idiots (some are, some aren't) but because software teams are often handed different sets of priorities before and after shipping, and those priorities often don't complement each other.
Then again, if Lucid let their software developers set the priorities, they'd have a perfect, bug-free, solid code base that works perfectly in their first shipping car—in 2040.
