Will the Tesla Roadster make its passenger motion sick?

By Dizzout editorial team5 min read

The short answer

One launch is brief: Tesla claims 0 to 60 mph in under 1.6 seconds for the Performance trim. What wears a sensitive passenger down is repetition, launch after launch, with hard braking and hard cornering in between. The Roadster helps in one way. Its only passenger seat is in front, beside the driver, which is the most settled seat in any Tesla. Launch runs belong on a closed course.

The new Roadster is built around the thing a motion-sensitive passenger dreads most: big changes of speed, on somebody else's timing. The numbers are huge. The time each one lasts is short.

So the useful question is less about any one figure and more about what you sit through, and how often.

How hard each trim pulls

Tesla gives 0 to 60 times, not g figures. We worked out the average acceleration each claimed time implies, using 60 mph as 26.82 meters per second and 1 g as 9.81 meters per second squared. The Model S Plaid is in the table for scale.

TrimSeats0 to 60 mphAverage over the run
Roadster Performance2Under 1.6 seconds (Tesla claim)At least about 1.7 g
Roadster Thrust2Under 0.9 seconds (Tesla claim)At least about 3 g
Roadster Rocket1Under 0.59 seconds (Tesla claim)At least about 4.6 g
Model S Plaid, for scale5About two seconds (rated)About 1.4 g
Average acceleration per Roadster trim, with the Plaid for scaleAverage over the run, worked out from the claimed time; Tesla has not published g figures. Plaid time and seats from Wikipedia.

Two words in that table carry weight. "At least", because Tesla says under each time rather than exactly it. "Average", because a launch does not pull evenly, so some moments of a run pull harder than the figure.

The Rocket's number is the one nobody rides along for. It has one seat.

Why a launch still gets you

A launch lasts a moment, and it still lands harder than its length suggests. Motion sickness comes from a mismatch between what your inner ear feels and what your brain expected, and a launch widens that gap in three ways.

  • No sound cue. An electric car has no engine note rising to warn you. The same gap shows up at the other end: lifting off slows a Tesla firmly through regenerative braking, with nothing to warn a passenger. Our Tesla guide covers that part in detail.
  • Your head pitches. Hard acceleration pushes your body into the seat and your head follows a moment later, unless it already rests on the headrest. Hard braking throws it the other way. Each movement is one more thing for your inner ear to report.
  • You did not choose the moment. The driver knows exactly when the car will go. You find out a beat later. That gap is why drivers rarely get car sick and passengers do.

Downforce and cornering

Tesla claims Track Mode downforce "approaching F1 levels". Downforce presses the car onto the road. More grip lets the car corner and brake harder, so a passenger feels stronger side loads in fast corners and a harder shove forward under braking.

Tesla has not published cornering figures, and we have not estimated any. What is clear is the shape of a track session: hard corners and hard stops, lap after lap. A launch lasts seconds. A session of hard laps is the long, repeated exposure that wears a sensitive passenger down.

The flip

Tesla's description of the car includes the line "Soโ€ฆyes, it can fly." Teslarati reports that in the demo the car drove up a curved ramp until it was upside down, flew off, flipped and landed. Electrek describes it flipping through the air.

Of the three trims, Tesla describes thrusters for upward acceleration and lateral rotation only on the Rocket, and the Rocket has one seat. If a car is going to do that, nobody is riding along.

How to ride it well

Everything here assumes a closed course. Launch runs, hard braking and flat-out cornering do not belong on public roads.

Riding along for a launch

Do

  • Ask the driver for a countdown before each launch
  • Rest your head against the headrest before the go
  • Look up and far ahead through the windshield
  • Agree on a small number of runs before you get in

Don't

  • Look down at a phone between runs
  • Push on once the first yawn or cold sweat arrives
  • Ride along for a launch on a public road
  • Brace with your head held forward off the headrest

Practical habits, not measured effects. The horizon and phone advice match our remedy verdicts.

The eyes matter most. Our verdict on looking at the horizon is that it is the best-supported free fix there is, and putting the phone away is the easiest change most people can make. The countdown borrows the driver's advantage: motion you can predict is easier to sit through.

If you feel it starting anyway, Dizzout is one option for the passenger seat. It plays sound therapy through any headphones. It is drug-free, with no drowsiness, and relief in about 90 seconds.

Frequently asked questions

Can a car launch make you motion sick?

It can add to it. A hard launch is acceleration you did not choose, with no engine note to warn you, and it pitches your head. One launch is brief. Repeated launches, hard braking and hard cornering are what wear a sensitive passenger down.

How many g does the Tesla Roadster pull?

Tesla has not published g figures. Worked out from its claimed 0 to 60 times, the average over the run is at least about 1.7 g for the Performance trim, at least about 3 g for the Thrust and at least about 4.6 g for the Rocket. For scale, the Model S Plaid, rated at about two seconds, averages about 1.4 g.

Can you ride as a passenger in the Roadster Rocket?

No. Tesla describes the Rocket as a one-seat car, and Electrek reports that Tesla's Roadster page says it is not approved for public roads. The Performance and Thrust trims have two seats.

How should a passenger ride along for a launch?

On a closed course only. Ask the driver for a countdown before each launch, rest your head against the headrest, look up and far ahead with the phone put away, and agree on a small number of runs before you start. Stop at the first yawn or cold sweat.
