Segway

This is an electric motorised scooter thingy, isnt it?

Or has it now officially replaced the word “segue”?

Pls advise before I go into meltdown with the BBC.

It would be much better if words were all spelled phonetically, but as it happens yes a segway is a type of scooter. 

They and their users went through a period of being the object of mockery (when they were new, about ten years ago) and briefly became pretty much the least cool things on earth. But over time people have realised how neat it is being able to roll around standing up.

Didn't the inventor die while riding one? Have they fixed whatever design flaw led to the mishap?
