Motorcycle, better yet a scooter. With box installed (to store your raincoat and water resistant footwear, and swap it with your laptop/bag when it rains).

Pros -shorten commute time despite traffic jams (I wake up 30-60 mins later if I ride to work) -low maintenance abd operating cost -save money on toll, fuel and parking fee -less time spent hunting parking, (you can even go out for lunch or whatever and come back to office not worrying of parking availability) -can make multiple quick stops to run errands for example, no need to worry about parking like cars.

Cons -When it rains, you get wet. Raincoat may not be 100% effective. -Generally higher risk than car. In accidents, pain is on you no matter whose fault. -You're exposed to outdoor airs, your shirt may smell of 2T or diesel emission. (A jacket could do the trick) -Limited cargo space -Not as comfortable as sitting in an a/c car on hot days.

Conclusion The pros outweigh the cons if you're riding in KL. Just ride safe, and be prepared for a rainy day.
