This might seem trivial but to me it raises questions about the quality of engineering and testing that goes in to in-vehicle software systems. If a subtle off-by-one error like this slipped through to release, what about a subtle off-by-one error in the system that handles the brakes? In these systems a "crash" can be a literal one. Even if the other systems are engineered to much more stringent standards, I'd argue that the user-facing part should meet the same standards, so the driver has confidence they're driving a safe vehicle and not a buggy pile of hacks.
