While its certainly good to know about such potentials, this may [ultimately] not be the problem at all, in reality.
Why? Because even if his Lexus did have this system (either a lidar-based lane-departure or ACC) and the mounting locations were problematic in this regard, I suspect, they could probably be disabled or "fused-pulled."
If not, at least these new radar detectors have ASICs
which can be easily updated by software (ie; firmware) to have the specific pulse trains pre-filtered out. That's one of the great features of the latest generation of radar detectors, field-updateability by the user/owner.
I am already pleased to have experienced that the latest
firmware, for both of the remote radar detectors from Beltronics and Escort, has successfully eliminated the falsing created by the POP-profile-like 24.1ghz (K-radar) based adaptive cruise control and/or lane departure systems
used in models like Audi's side-assist. Kudos to the engineering teams for effectively mitigating this problem that we first documented nearly two years
ago. I was hoping Audi NA would have seen to it (as I communicated directly with their executive management and their senior engineers about this) but am pleased to see Escort/Beltronics take the initiative.
If Escort (and Beltronics) haven't already specifically filtered these lidar sources, they certainly will, soon enough. Whistler has long-ago addressed these systems with their advanced LSID feature of the Whister XTR-695
and future models.
Of course, lidar falses occur on these sensitive laser detectors/laser jammers more so than windshield-mounted models, primarily due to their external mounting locations.
It is fairly common to get a front (or rear false) on either the Beltronics STi-R or the Escort Passport 9500ci when the sun is lower in the sky and being eclipsed by passing trees (whose recurring shadows at a specified frequency/speed) which can create the appearance of a police laser pulse-train (and it occasionally happens on the more sensitive windshield-mount laser detectors, too).
It's something that you get used to. At least
with the knowledge that the laser shifters (or laser jammers) are doing their function (and having Veil G4 on as well), there's no urgency to stab the brake
when it happens, making you a safer driver
, in the process.
