if i hit a bump, quite often all 4 wheels shimmy until i pull the steering wheel back and forth. Irritating and embarrassing

My home screen upon entry used to be the vehicle screen. Now it is the climate control screen. Is that omething I can change or a permant change from latest software update.

Neither of those things are normal. Time to schedule service.
 
I find if I put the go pedal to the floor, the car begins shimmying and the steering wheel becomes squirmy...

Aaah, it's great to be alive!!!

Can you clarify what you mean by hitting a bump? I’m wondering if the lane departure warning is being activated, where the steering wheel feels like you are driving over rumble strips.

Can you try turning off the lane departure warnings and see if you get the same effect?

It’s most likely this. the lane departure warning is pretty sensitive.
 
Same. Is this normal? Anyone else?
i'd say some degree of shimmying and squirming under full throttle is expected for a vehicle in this power class as various systems optimize for acceleration against tire- and surface-limited traction. i just want to feel something again, dammit! make me feel alive!

hats off to lucid engineering for making this kind of power accessible in a daily-drivable family vehicle, not to mention with a single pedal versatile enough to command the broad spectrum of moderate braking to full power. the acceleration curve that gradually builds to peak power without roasting the tires really helps keep drivers of modest ability feeling heroic - and more importantly, alive.

i don't think you'd have a shimmying-free/squirming-free time applying this level of acceleration on everyday, less-than-perfect public roads in most any road vehicle of this power class, and i don't hunt for glass-smooth asphalt in my GGT like i might in a sports car. once the acceleration event is over and you are just cruising at speed, the chassis yawns with boredom.

most cars making this kind of power usually end up in a ditch.
 
I turned off that lane departure intervention the 1st day...can't stand some techy robot "thing" pulling on my steering wheel ...oh HELL no!!
Just the warning is enough although its getting annoying as well

When I took drivers ed it was "mirror, signal, blindspot"...then go. Not a fan of this type of ADAS

They missed the part about staying inside the lines? :p

My last class (2 weeks ago) was "accelerate, brake hard, trail brake, hit apex, unwind wheel while accelerating and repeat". Too much fun!

Turned off LDW and still have shimmy when in my lane and hit a minor rough spot. 10 to 15 seconds and goes away
 
@tmichael will you tell us more about the race day? Is that an Atom?
It's a Radical SR3 XXR. Took a 3 day course, starting with basics in road cars and advancing to governed Radicals, removing the governors in day 2.

I've taken a 3 day at Radford in AZ in Road cars, with lead and follow early on, ending with real racing, albeit passing on straights only.

This class ended with me eligible for a SCCA novice license and practiced side by side racing, requirement for knowledge of flags, ability to exit a car in a certain number of seconds when there is fire, etc.

Totally a blast! The private track with condo garages has opened up the course to a membership option where I have access to the track 4-5 days a week and can drive my own (won't be doing that) or rent any of their road cars (Great cars - see link below to track info) or one of their 4 Radicals.

It's all pricey, but renting is cheaper than buying and maintaining a race car for local races and the Radical offers that open cockpit, tubular frame thrill at a track that is 15 minutes from me. I can't afford to do it every week, but if I can get a 3 hours session in every 3 weeks or so during the season, I'll scratch the itch for thrills and be able to improve my lap times as the season progresses. Think of it as golfing two rounds at Pebble Beach. I'm not a golfer, but I find this wildly fun while I can improve my skills. The record for this track in a Radical is 1:06 and I had a 1:13 (not repetitively) - but, you all know that taking 6 seconds off of 73 seconds is not easy. It could be years before I can get in striking distance of that time, let alone doing it repeatedly. And, at 71, my reflexes will only slow, so I'm on a short time frame for getting close. All good goals!

This year, they have added sessions running counter-clockwise on the track, so once I start feeling like I am improving, I'll reverse the direction and be right back to zero. Too Much Fun!!!

Dream Ahead!

Now, back to shimmy conversation... 🧦
 
How expensive is that ? ;)
$350-$650 per hour, depending on car chosen. Starts with Toyota GR86 (setup with racing tires, brakes, etc.), up through Mustangs, Supra, Alfa, Porsche Caymans, Corvette, BMW M2 Competition, Lotus Emira and Radicals. No car cost, no gas, no brake pads, no oil changes, no tires with rentals - just thrills.
