You might have witnessed an Ambulance with backward spelling written on it.

[{ "selector": ".mbztj-a", "duration": "500ms", "fill": "forwards", "delay": "500ms", "keyframes": [ {"offset": 0, "transform": "translateY(-399.0833333333335px)", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }, { "selector": ".fnidj-a", "duration": "500ms", "fill": "forwards", "delay": "1250ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": "1"} ] }]

This backward spelling is always on the front side of the Ambulance.

[{ "selector": ".sjple-a", "duration": "500ms", "fill": "forwards", "delay": "500ms", "keyframes": [ {"offset": 0, "transform": "translateY(calc(600px - 198px))", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }, { "selector": ".ntois-a", "duration": "500ms", "fill": "forwards", "delay": "750ms", "keyframes": [ {"offset": 0, "transform": "translateY(calc(600px - 213px))", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }, { "selector": ".azoza-a", "duration": "500ms", "fill": "forwards", "delay": "1000ms", "keyframes": [ {"offset": 0, "transform": "translateY(calc(600px - 249px))", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }, { "selector": ".oqxfx-a", "duration": "500ms", "fill": "forwards", "delay": "1250ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": "1"} ] }]

You might've also seen that cars and bikes have sides & rare mirrors are convection mirrors.

[{ "selector": ".urdjw-a", "duration": "500ms", "fill": "forwards", "delay": "750ms", "keyframes": [ {"offset": 0, "transform": "translateX(-290px)", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }, { "selector": ".anczq-a", "duration": "500ms", "fill": "forwards", "delay": "1000ms", "keyframes": [ {"offset": 0, "transform": "translateX(-269px)", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }, { "selector": ".zbxfb-a", "duration": "500ms", "fill": "forwards", "delay": "500ms", "keyframes": [ {"offset": 0, "transform": "translateX(-320px)", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }, { "selector": ".wxnlr-a", "duration": "500ms", "fill": "forwards", "delay": "1500ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": "1"} ] }]

And when the Ambulance is optical in the mirror, it will be posterior.

[{ "selector": ".lcuxa-a", "duration": "500ms", "fill": "forwards", "delay": "650ms", "keyframes": [ {"offset": 0, "transform": "translateY(calc(600px - -1px))", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }, { "selector": ".wmgrx-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(-577px)", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }, { "selector": ".bjmbf-a", "duration": "500ms", "fill": "forwards", "delay": "1650ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": "1"} ] }]

It is the cause that Ambulance spelling is written backwards.

[{ "selector": ".ckdib-a", "duration": "500ms", "fill": "forwards", "delay": "650ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": "1"} ] }, { "selector": ".gqrdm-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(calc(600px - 384px))", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }, { "selector": ".ubxsg-a", "duration": "500ms", "fill": "forwards", "delay": "1000ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": "1"} ] }]

The spelling is written in green or blue colour.

[{ "selector": ".ktbwq-a", "duration": "500ms", "fill": "forwards", "delay": "500ms", "keyframes": [ {"offset": 0, "transform": "translateY(calc(600px - -15px))", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }, { "selector": ".qzmor-a", "duration": "500ms", "fill": "forwards", "delay": "500ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": "1"} ] }, { "selector": ".adjxf-a", "duration": "500ms", "fill": "forwards", "delay": "500ms", "keyframes": [ {"offset": 0, "transform": "translateY(-551px)", "opacity": "1"}, {"offset": 1, "transform": "translateY(0)", "opacity": "1"} ] }, { "selector": ".zndcx-a", "duration": "500ms", "fill": "forwards", "delay": "1250ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": "1"} ] }, { "selector": ".dmzct-a", "duration": "500ms", "fill": "forwards", "delay": "1000ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": "1"} ] }]

These colours can be far-sighted because of their wavelength.

[{ "selector": ".opwnl-a", "duration": "500ms", "fill": "forwards", "delay": "750ms", "keyframes": [ {"offset": 0, "transform": "translateX(calc(360px - 84px))", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }, { "selector": ".mjele-a", "duration": "500ms", "fill": "forwards", "delay": "1000ms", "keyframes": [ {"offset": 0, "transform": "translateX(calc(360px - 83px))", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }, { "selector": ".bwgit-a", "duration": "500ms", "fill": "forwards", "delay": "500ms", "keyframes": [ {"offset": 0, "transform": "translateX(calc(360px - 70px))", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }, { "selector": ".btgrp-a", "duration": "500ms", "fill": "forwards", "delay": "1500ms", "keyframes": [ {"offset": 0, "transform": "translateX(calc(360px - 121px))", "opacity": "1"}, {"offset": 1, "transform": "translateX(0)", "opacity": "1"} ] }]
