01 The back seat

Drivers rarely get carsick. Passengers do.

You hold the wheel, so your body knows every bend before it comes. The people behind you only feel the car sway.

Cruiso measures what the back seat feels, and tells you when it starts to build.

02 The rhythm

Carsickness has a rhythm.

Not the bumps you notice. It's the slow sway, a wave every few seconds, that your inner ear can't square with what your eyes see.

Cruiso reads your phone's motion sensors 50 times a second and weighs that sway the way the ISO 2631-1 ride-comfort standard does.

03 The dose

Every bend adds to the dose.

Motion sickness builds up over a trip and doesn't reset on the next straight. Cruiso adds it up as you drive, as a motion sickness dose value, and shows it as one number and five calm colours.

  • SSafeAlmost no one feels symptoms
  • MMildSensitive riders may notice it
  • MdModerateAbout 1 in 4 riders feel queasy
  • HHighMost riders feel queasy
  • SvSevereRiders likely to feel sick — slow down

04 The word

One calm word at the right moment.

No beeps, no nagging. When the ride starts to build, Cruiso says one short sentence, then lets you drive.

Ease off the brakes · Ease onto the gas · Brake before the bend · Winding road · Rough road

Winding road: slow down by about 15 km/h for about 40% less motion sickness.

Nice and smooth: about 20% less motion sickness.

05 Arrival

Arrive with everyone feeling fine.

Cruiso listens to every bend and speaks only when it helps. The back seat gets a calmer ride, and you get to keep driving.
