The reading and the lecturer talk about the bike lanes. However, the reading only says talks about the positive points of bike lanes whereas the lecturer explains the negative points of bike lanes taking with the example of bike lanes in San Francisco as an example.
First, the lecuturer believes that the bike lanes are not eco-friendly. Since commuting by bike is too physically demanding, the percentage of people who participate in commuting by bikes is less than 1 %. Thus, making bike lanes do not contribute to reducing pollution made on the road. This point shows that building bike lanes is are not helpful for the environment.
Second, he argues that drivers on the roads with bike lanes will be more stressful than before. After making bike lanes on the main roads, very few people are joining to commute by bikes and drivers already had traffic congestion before the bike lanes so cars on the roads are still same as it was before having bike lanes. That is The reason why drivers are frustrated is that because they give their invaluable roads to only a small number of very few some's bikes. This reponds to the point that drivers will be better off since more people commute by bikes, if a city builds bike lanes.
Finally, He claims that bike lanes rather increase traffic accident unlike the an expectation of the reading. To illustrate this, he gives an example that when cars pull over on the road, bikers do not consider much, because bikes think that bike lanes are theirs, so they do not need to worry about it. Therefore, bike lanes actually cause rather make more accidents than before. While saying that San Franciso god get rid of the bike lanes, he concludes his opinion saying that bikes lanes are not beneficial.
