I sympathize and hope you could find out how to cycle to work; as a side note, however, a "nice road bike" is not very good for commuting 2.5 miles to work.

1) road bikes are not good for taking you and a laptop a short distance to work; they are optimized for doing long journeys on free roads, not city traffic. What you want is a bike where you sit upright and which enables you to look around more conveniently, a bike with no clip pedals which enables you to stop at traffic lights at ease, and a bike with a rack which enables you to put your bag on it, etc.

2) a nice bike will be stolen in no time unless you keep it in closet (even here, and my country/city has actually very little crime).

That said, I understand your problem if roads are too scary. Where I live I have a dedicated bike/pedestrian lane 98 % of my work commute (10 km) and I mostly use a cyclocross bike which is almost like a road bike (slightly more agile, because there are many turns and crossings on the way, but I do use clip pedals).

Too often people buy "fashionable" bikes for commute (a carbon-fibre road bike, a BMX or downhill bike, or a fat bike) when the best one would be a cheap, general-purpose hybrid bike that rolls relatively easily but can take you across stone slabs or grit without puncture, and has a relatively upright sitting position with efficient access to pedals.
