I believe the drive alone data is car specific, with bicycle and motorcycles a separate choice.

Subject: [CTPP] No Car but Drive Alone to Work

I'm hoping someone can help me address this question from a colleague.
He put together a table from the 2006-2008 ACS showing mode of journey
to work by vehicles owned and came up with surprisingly large numbers
who do not won a car yet drive alone to work. No doubt, there are a few
people who fit this category but my guess is that this largely is the
result of either people misunderstanding the question or some sort of
coding problem. Here is an excerpt from his email ( the Cambridge here
is Cambridge, Massachusetts):

I'm looking at ACS data and specifically at cities and percent workers
have no car available.  From that I'm then looking to see how those
workers get to work.

The attached worksheet shows my work.  What is strange is that it shows
for Cambridge that 6.6% of people without a car available drove alone to
work.  The percent is similar to Boston. And NYC has 3.4% of workers
with No vehicles available driving alone to work.

So, the question is, how can someone without a vehicle drive to work
alone?  Do you have any ideas on this?  It could be someone doesn't own
a vehicle, but drives a friend's car to work. Or has no car of their
own, but uses a company car to get to work.  But seems like a high
number for this.

Can anyone shed any light on this?

Thanks

Cliff Cook
