Had my first scary glitch/ lag while switching Drive Modes today

[Rizzian]

Not sure if anyone else has experienced something like this:
I was bored in a drive-thru line so I started messing with the drive modes. Normally I'm an All-Purpose guy with the occasional "Sport" mode. I never did "Snow" before, so what I figured "what the heck."
Wow, that's higher than I expected! Is off-road even higher? I click past the off-road warning and the R1S defaults to "All-Terrain" mode with the suspension on "Highest." Now navigating the parking lot, I note how the steering is different... It seems like I have a slightly tighter turning radius (or maybe it's just that there is no haptic feedback or "pushback" from the steering wheel). I have to manually rotate the wheel back to 12 o' clock after turning instead of just hitting the gas and allowing the wheel slide through my fingers, rotating back to its default position. I really want to go offroad and see what "Drift" is about some day, but now I'm exiting the parking lot and need to merge onto a divided highway. I click back to "On Road" as I pull forward, cross two lanes of (oncoming) southbound traffic, and come to a stop in the middle of the divided highway to wait for an opening in the Northbound lanes.

I was expecting my RiS to be back at "All-Purpose", however, drive modes must default back to the last used setting when going between On-Road and Off-Road. Consequently, I'm back on "Snow" mode. That won't do with traffic approaching from both sides, so I hit "Sport" and allowed a couple of seconds for the chassis to drop. I see an opening to merge and hit the accelerator, which gives a light pull, then nothing It just feels like it's coasting. Now I'm completely merged onto the inside, northbound lane of a 4-lane divided highway, but the R1S isn't accelerating. I'm doing about 20 with a pack of cars bearing down on me from behind at about 60MPH. I aggressively throttle the pedal, twice, but nothing happens. Under normal circumstances, I would be hitting 90 right now, but the Rivain feels like it's just coasting and the speedometer is reading low 20's. It feels like when your engine stalls in an ICE vehicle. I lay off the accelerator and keep shifting my gaze between my speedometer and the approaching wave of traffic in my rearview. I am contemplating turning on the hazards and rolling into the grass median when the accelerator pedal begins responding again.
Looking back, the whole ordeal from pulling out of the parking lot to getting back up to speed on the divided highway was probably only 6-10 seconds.

If I had to guess what happened, the accelerator function got reset or was somehow lagging behind my mode changes. Was it just a software hiccup? Was the accelerator still stuck in "Snow" mode but the suspension had moved on to "Sport?" IDK if normal operation for Snow Mode is to have a very gradual acceleration curve and very little torque (to keep the wheels from spinning on snow and Ice). If you bury the accelerator in Snow mode, does the car just coast?
There were no warnings or notifications. Just a couple of seconds of me freaking out while the R1S accelerator became seemingly unresponsive as traffic approached.
Everything else about the drive home after that was unremarkable.
Has anyone else experienced something like this?
Thanks.

sounds like you were in off-road mode? Snow mode doesn't really feel that much different

Your truck was still settling from being in Highest mode. In Highest, your speed is limited to 20 mph, and it takes several seconds after leaving that mode to get the speed limiter removed. Once the limiter is removed, you have to release the throttle and then press it again to go.

Yep, switching from off road takes a moment. I’ve had issues with it not switching no matter how long I wait. Had to do a reset last time. Typically you have to be under 20 mph to switch out of off-road. Drift mode is wild. Find a spot to try all of the settings. Highest is the max.
