I'm in Tel Aviv for work. I see there is some data for here, but only of main roads. I'd like to get some traces, but it can be hard to find the time on a brief visit. My best chance would be to collect data whilst riding taxis to the office, but does that work very well?

I'm slightly wary of arousing suspicion. This is a very security conscious place and they may not react well to a foreigner collecting that sort of information. Not that I plan to go near any sensitive areas.
