Problems solved by technology

But the biggest defect of this kind of walking-replacing tool is that the electric walking-replacing tool does not make any sound when driving on the road; therefore, people cannot avoid it in time because they cannot hear the sound, resulting in frequent traffic accidents
The people’s calls for the above-mentioned speed limit and prohibition of electric vehicles are endless. Relevant news reports and Phoenix TV have also held a special discussion on this, and no conclusions have been reached on the support or opposition of the speed limit ban.
