ugh, these fights are why I finally quit contributing to wikipedia. You spend more time arguing about the increasingly complex administrative rules than actually creating content.
Given the policies those who want to delete the article cite (WP:ONEEVENT and WP:NOTNEWS) it might make more sense to create an article about the event. The Kish information in the current article could be included along with information about Lin (he had a compelling life story and might deserve some internet recognition anyway), and maybe some background on cyclist/driver relations in pittsburgh if you can find sources that meet the verifiability guideline. Good luck.
