Final answer:
The author includes Crewse's quote to underscore the minimal regulatory environment for e-bikes, potentially supporting arguments for their accessibility or suggesting a need for more regulation.
Step-by-step explanation:
The author quotes Legrande Crewse stating, "[the e-bike is] one of the very unique categories of vehicle that there really isn’t any kind of onerous regulation." The inclusion of this quote serves to highlight the lack of strict regulations governing e-bikes compared to other vehicles.
This could be used to support an argument for the ease of use and accessibility of e-bikes or to suggest the potential need for more oversight in this area.
For instance, in the context of Issa's research, it might buttress the case for greater access to trails by emphasizing that e-bikes do not come with the same regulatory challenges as other vehicles.
However, in drawing parallels to other discussions about regulations, such as the DOT's non-discriminatory policies towards people with disabilities, or the design team's definition of their problem surrounding the creation of an environmentally friendly commuter vehicle, the author provides a broader scope on how vehicles are generally discussed in regulatory terms.
